    the do-it-yourself science kit simple
  • 00:01:12
    experiments you can do at home new from
  • 00:01:14
    DIY
  • 00:01:16
    side science is wonderful it's in
  • 00:01:19
    everything we see feel and touch science
  • 00:01:22
    is how we learn about the world with
  • 00:01:24
    science we found out that all of our
  • 00:01:26
    food comes from plants and plants make
  • 00:01:29
    their own food from air water and
  • 00:01:31
    sunlight by watching clouds drift and
  • 00:01:33
    ice melt we discovered that matter
  • 00:01:35
    exists in only three phases we found out
  • 00:01:38
    that dinosaurs once roam the Earth by
  • 00:01:40
    looking closely at rocks we learned that
  • 00:01:42
    our sun is a star just like all the
  • 00:01:45
    other stars in the sky at night by
  • 00:01:46
    watching them rise and set every
  • 00:01:50
    day we watched shadows and figured out
  • 00:01:52
    that our world is a spinning ball we
  • 00:01:56
    invented clocks there are a lot of
  • 00:01:58
    experiments that you can do at home to
  • 00:02:00
    learn about huge scientific ideas you
  • 00:02:02
    don't need a special lab your lab can be
  • 00:02:04
    anywhere because science is something we
  • 00:02:06
    do all the time everywhere we go and
  • 00:02:09
    then we'll go into spot bowling and
  • 00:02:10
    picking up fair
  • 00:02:12
    Elizabeth I'd like very
  • 00:02:16
    few not only that scientific principles
  • 00:02:19
    hold true everywhere we go that's right
  • 00:02:21
    a good science experiment is
  • 00:02:26
    repeatable try this get a big bowl and
  • 00:02:30
    fill it with ice
  • 00:02:32
    [Music]
  • 00:02:42
    water now get a 2 L Pot bottle with its
  • 00:02:45
    cap and fill this with very hot
  • 00:02:53
    water H let the bottle sit for a few
  • 00:02:57
    moments
  • 00:03:00
    [Music]
  • 00:03:06
    now dump the hot water
  • 00:03:10
    out and put the cap on fast I mean right
  • 00:03:13
    now look at he split and put the bottle
  • 00:03:15
    in the icy cold
  • 00:03:19
    bowl look the bottle collapsed now why
  • 00:03:23
    is that well when you dump the water out
  • 00:03:25
    it's not filled with air it's filled
  • 00:03:26
    with an invisible gas water vapor and
  • 00:03:29
    when you cool it the water vapor turns
  • 00:03:30
    to liquid water Now liquid water takes
  • 00:03:32
    up hardly any room at all compared with
  • 00:03:34
    water vapor so the air in the atmosphere
  • 00:03:36
    crushes the bottle like a Giant's
  • 00:03:41
    fist anyway the atmosphere is Big so the
  • 00:03:45
    effect is Big come with
  • 00:03:50
    me warm air takes up more space it
  • 00:03:53
    expands cool air takes up less space
  • 00:03:56
    cool air contracts
  • 00:03:59
    [Music]
  • 00:04:05
    take a look at
  • 00:04:08
    this it's our great
  • 00:04:10
    big atmospheric container crushing
  • 00:04:13
    experiment of science but now instead of
  • 00:04:15
    using a plastic bottle from the kitchen
  • 00:04:16
    we use this big metal
  • 00:04:19
    drum first we lower it onto the heat
  • 00:04:22
    kids this Barrel thing can be dangerous
  • 00:04:23
    so stick to the pop bottle okay then we
  • 00:04:26
    put in a little water
  • 00:04:33
    [Music]
  • 00:04:37
    now we wait while the water boils and
  • 00:04:39
    the steam drives all the air from inside
  • 00:04:42
    the metal
  • 00:04:45
    drum that ought to do it now we take it
  • 00:04:48
    off the
  • 00:04:55
    heat and we seal it up with this it's
  • 00:04:57
    called a bun and that hole would be the
  • 00:05:03
    mhm now all we got to do is cool it
  • 00:05:27
    off I crushed it like a giant it's fist
  • 00:05:30
    a good experiment is repeatable it's
  • 00:05:37
    science that's liquid air boiling at a
  • 00:05:40
    temperature of
  • 00:05:42
    190° below 0 cenr now I know you're not
  • 00:05:46
    used to seeing air as a liquid but uh
  • 00:05:50
    temperature and pressure determine the
  • 00:05:52
    form and shape of most subst you'll also
  • 00:05:55
    see the effects that uh are obtained by
  • 00:05:58
    uh using it very
  • 00:06:02
    PRS that are notar associated with them
  • 00:06:05
    maybe there's an experiment we can do to
  • 00:06:06
    find
  • 00:06:08
    out you can see air pressure by using a
  • 00:06:10
    clear glass of water like this and a
  • 00:06:12
    piece of paper a postcard or a card like
  • 00:06:15
    this all you have to do is put the card
  • 00:06:17
    over the glass of water like this now
  • 00:06:20
    flip
  • 00:06:21
    it the air pressure in the room pushes
  • 00:06:24
    the card up against the rim and holds
  • 00:06:26
    the water in the glass all right now
  • 00:06:28
    we're going to try it with something
  • 00:06:30
    a little bit bigger fill it with
  • 00:06:38
    water now we do the same experiment and
  • 00:06:41
    put the card over the top and it should
  • 00:06:43
    work right cuz it worked on the smaller
  • 00:06:45
    one and it's the same experiment well
  • 00:06:47
    we'll just do
  • 00:06:48
    [Music]
  • 00:06:55
    it um
  • 00:07:00
    dad testing will sometimes show that you
  • 00:07:02
    have not made the right guess so you
  • 00:07:04
    keep on thinking and testing may I be
  • 00:07:07
    excused the
  • 00:07:10
    lunal
  • 00:07:14
    14
  • 00:07:16
    investigation what's he doing here he's
  • 00:07:19
    showing us that you can do science
  • 00:07:21
    anywhere you can yes yes son you can
  • 00:07:24
    investigate huge ideas with common
  • 00:07:26
    household items and a little Ingenuity
  • 00:07:29
    now not only that a good experiment is
  • 00:07:36
    repeatable when matter is a gas a lot of
  • 00:07:38
    the time you can't see it it's invisible
  • 00:07:40
    but here's a way to prove to yourself
  • 00:07:41
    and any of our fellow scientists that
  • 00:07:43
    invisible gas is matter we wait it first
  • 00:07:47
    take a look at this broomstick balance
  • 00:07:48
    of science it's a broomstick with a hole
  • 00:07:50
    in it there's a lunch bag tack to each
  • 00:07:52
    end now we need to make some invisible
  • 00:07:54
    gas this is an old trick but it's a good
  • 00:07:56
    one pour some vinegar into a pitcher
  • 00:08:00
    then add a little bit of baking
  • 00:08:04
    soda that fizzing is carbon dioxide gas
  • 00:08:07
    coming off it's the same gas that
  • 00:08:09
    bubbles out of our soft drinks even
  • 00:08:10
    though it's invisible you can still pour
  • 00:08:12
    it just like you pour water or milk pour
  • 00:08:14
    the invisible gas into one of the bags
  • 00:08:16
    it pours even though you can't see
  • 00:08:22
    it the gas is heavier than the air and
  • 00:08:25
    the bag on this end goes down it's
  • 00:08:27
    invisible but it's matter it's in the
  • 00:08:29
    phase of matter that we scientists call
  • 00:08:33
    gas and it's total science why all this
  • 00:08:36
    emphasis on observing things all science
  • 00:08:39
    begins with observation because
  • 00:08:41
    observation is one of the very best ways
  • 00:08:43
    to
  • 00:08:45
    learn here's a light trick that doesn't
  • 00:08:47
    need mirrors put a penny in a pie
  • 00:08:50
    pan now move back so you don't see the
  • 00:08:53
    penny don't move cuz I'm going to pour
  • 00:08:55
    the water
  • 00:08:58
    in it's okay if you make a
  • 00:09:01
    mess pretty cool
  • 00:09:03
    hey see light's always bouncing off the
  • 00:09:06
    penny but when you pour the water in it
  • 00:09:08
    makes the light Bend and the bending of
  • 00:09:10
    the light makes the penny reappear but
  • 00:09:12
    the penny didn't move through all of
  • 00:09:13
    this but don't take my word for it try
  • 00:09:16
    it son I think it's time we had that
  • 00:09:19
    talk about the birds and the bees uh
  • 00:09:22
    mom can I have a glass of water yes
  • 00:09:26
    Richie H that sounds tasty honey can I
  • 00:09:28
    have one too why of course dear
  • 00:09:33
    [Music]
  • 00:09:46
    [Music]
  • 00:10:04
    Hey look it's little air pressure
  • 00:10:05
    holding up the card under the glass of
  • 00:10:07
    water fast any experiment you can do at
  • 00:10:08
    home of science see the water in the
  • 00:10:10
    glass doesn't spill out because the
  • 00:10:12
    pressure of the atmosphere is pushing in
  • 00:10:14
    all directions at once so not only is it
  • 00:10:16
    pushing down on the glass it's pushing
  • 00:10:18
    up on the card and it's strong enough to
  • 00:10:20
    hold it
  • 00:10:24
    [Music]
  • 00:10:25
    there let's think about that this time
  • 00:10:29
    I'm going to get some
  • 00:10:31
    help
  • 00:10:32
    cool okay so now we put the card on top
  • 00:10:35
    and flip it
  • 00:10:40
    [Music]
  • 00:10:48
    [Music]
  • 00:10:56
    [Music]
  • 00:11:20
    exquisit here's how you can make an egg
  • 00:11:22
    tower all you need is an egg and a
  • 00:11:24
    couple of bottle caps take an egg and
  • 00:11:25
    put it between two bottle caps so that
  • 00:11:27
    you have a flat surface then balance a
  • 00:11:30
    book on
  • 00:11:34
    [Music]
  • 00:11:37
    top eggs are strong structures because
  • 00:11:40
    the weight is spread out all over the
  • 00:11:41
    eggshell this is an egg experiment you
  • 00:11:44
    can try at home give gives a brilliant
  • 00:11:46
    performance on the tracking an egg
  • 00:11:47
    structure with one egg was insect right
  • 00:11:50
    with three eggs take your eggs and place
  • 00:11:53
    them between two bottle caps arrange
  • 00:11:55
    them in a triangle then set something
  • 00:11:58
    heavy on top
  • 00:12:00
    [Music]
  • 00:12:09
    three eggs can hold more than one egg
  • 00:12:11
    because the weight of the book and the
  • 00:12:13
    Soup cans is spread out over all three
  • 00:12:15
    eggs eggs the one of Nature's Most
  • 00:12:18
    Beautiful structures and that's no Yol
  • 00:12:24
    [Laughter]
  • 00:12:30
    eggs are strong structures I'll bet
  • 00:12:32
    these eggs could even hold up cinder
  • 00:12:34
    blocks no I bet you're right set them
  • 00:12:36
    down one at a
  • 00:12:39
    [Music]
  • 00:12:54
    time eggs are amazing what
  • 00:12:59
    [Music]
  • 00:13:09
    Richie
  • 00:13:10
    Richard see that's the weight of The
  • 00:13:12
    Columns of the air that press down upon
  • 00:13:14
    the
  • 00:13:16
    Earth dad and at
  • 00:13:20
    highering less
  • 00:13:22
    and Dad it might even take you 10
  • 00:13:26
    minutes Richie what is it why do my
  • 00:13:28
    clothes always get stuck together when I
  • 00:13:29
    dry them it's just not
  • 00:13:33
    fair here are two fun things you can do
  • 00:13:36
    with your hair and a comb one cut a
  • 00:13:38
    square paper tape it in a roll like
  • 00:13:41
    this then comb your hair very
  • 00:13:46
    fast hold the comb near the
  • 00:13:51
    paper wow
  • 00:13:54
    needle am I having a bad hair day or
  • 00:13:57
    what two comb your hair again now hold
  • 00:14:01
    the comb near running
  • 00:14:02
    [Music]
  • 00:14:06
    water the water bends electrons went
  • 00:14:09
    from your hair to the comb all those
  • 00:14:10
    extra electrons are what pulled the
  • 00:14:12
    paper the comb build up a negative
  • 00:14:14
    charge that's what pulled the water
  • 00:14:15
    molecules
  • 00:14:19
    static well Richie let me show you
  • 00:14:26
    something hey let me try
  • 00:14:30
    what Richie doesn't realize is that he
  • 00:14:31
    and Dad have entered the static
  • 00:14:33
    electricity Zone a Zone where water
  • 00:14:35
    molecules allow electrons to flow from
  • 00:14:37
    one surface to another in this case the
  • 00:14:40
    sock was negative it had extra electrons
  • 00:14:42
    the shirt was positive it had fewer
  • 00:14:44
    electrons the water molecules allowed
  • 00:14:47
    the electrons to flow they evened out
  • 00:14:49
    the charges
  • 00:14:51
    neutralized you know this doesn't just
  • 00:14:53
    happen in the static electricity this
  • 00:14:54
    happens all the time I mean you can
  • 00:14:55
    repeat this experiment yourself hey Bill

    it's
  • 00:15:02
    science let's try an experiment perhaps
  • 00:15:04
    your mother will let you perform this
  • 00:15:06
    experiment in her kitchen all you'll
  • 00:15:07
    need is a toy balloon and a tea kettle
  • 00:15:09
    of boiling
  • 00:15:11
    water here's an experiment that shows
  • 00:15:13
    how the salty ocean makes things float
  • 00:15:19
    better a raw egg won't float in fresh
  • 00:15:21
    water but if you pour some salt water in
  • 00:15:23
    a glass
  • 00:15:29
    it floats it floats it floats that's
  • 00:15:31
    because salt water has more stuff in it
  • 00:15:33
    so it can hold up the egg science
  • 00:15:36
    Rules we put the card over the
  • 00:15:39
    [Music]
  • 00:15:45
    top and flip it
  • 00:15:49
    [Music]
  • 00:16:04
    W check it out it
  • 00:16:15
    [Music]
  • 00:16:22
    worked science is everywhere in the
  • 00:16:25
    trees and birds and the air you can
  • 00:16:27
    experiment with everything discover is a
  • 00:16:29
    lovely thing watch the clouds Flow by
  • 00:16:32
    and think of water Raper in the sky the
  • 00:16:34
    water that you boil on the sto makes a
  • 00:16:36
    cloud and then begins to
  • 00:16:41
    r on the
  • 00:16:43
    [Music]
  • 00:16:52
    sh if you experiment repeatedly and get
  • 00:16:55
    the same results continually then you
  • 00:16:56
    know that your Discovery has been a
  • 00:16:59
    successfully if you experiment
  • 00:17:01
    attentively you can make a great
  • 00:17:03
    discovery say you want to make a snazzy
  • 00:17:05
    boat experiment to see what things will
  • 00:17:07
    flow do it yourself
  • 00:17:11
    science on the sh science
  • 00:17:15
    [Music]
  • 00:17:35
    well Partners that's our show thanks for
  • 00:17:37
    watching to excuse me I'm going to show
  • 00:17:39
    myself some scientific principles with
  • 00:17:40
    stuff I find around the house today it's
  • 00:17:42
    the angular momentum of flexible systems
  • 00:17:44
    see
  • 00:17:47
    you it's
  • 00:17:50
    repeatable produc in association with
  • 00:17:53
    the National Science
  • 00:17:55
    Foundation First what you do p them up
  • 00:17:57
    on the site bring it across your body
  • 00:18:00
    Palm down then you turn your palm over
  • 00:18:03
    into back there you know lady you've got
  • 00:18:05
    a lot of hair you want to look through
  • 00:18:07
    the loop that's what you want to do
  • 00:18:08
    you're a little close to me I can't
  • 00:18:09
    quite get the loop between you yeah
  • 00:18:11
    there and let it happen yes that's
  • 00:18:13
    really good man you look at your taret
  • 00:18:15
    you throw overand kind of like you throw
  • 00:18:16
    a ball yes yes yes all right two three
  • 00:18:21
    go that's not bad okay ow
  • 00:18:40
    it's a cut okay good
  • 00:18:44
