[SOUND EFFECTS PLAYING] [MUSIC PLAYING] Take a plate of milk, and
drop some food coloring into the middle– as many
different colors as you want. Take a Q-tip covered
in soap and dip it right into the center
of the food coloring to make fireworks. That is awesome. Science. [SOUND EFFECTS PLAYING] This one I discovered
by chance the other day while I was drinking coffee. I was clicking
the little stirrer across the surface
of the coffee, and I noticed these crazy
little balls appearing. So I went home to try to it
again, and nothing happened. I tried a few different things
to recreate the spheres, including mixing
soap into my coffee. And sure enough,
there they were again, which makes me wonder what was
in my coffee the other day. So it seems to be
this soapy film that causes these little
spears to form, and the motion of
the water tends to make the spheres last longer. It works on the milk and
food coloring plate as well. You might try it
with other liquids. This is a pretty
interesting phenomenon that I had never heard of. If you have any guesses as to
what it is, leave me a comment. [SOUND EFFECTS PLAYING] This one’s fun. Make a little boat
out of a card, and then place the boat on
the surface of the water. Now, use your soap to break
the surface tension and power the boat. [SOUND EFFECTS PLAYING] Take an open jar full of water,
and put a card over the top. Flip it over, and it
will hold up the card. Now, this is a pretty
well-known trick. But what about this one? The water stays in the jar. Oh, yeah. I forgot to mention
that there’s a screen on the top of this one. I switched them. Tricked you! I screwed the top of
the jar over the screen so that it’s on
there really tight. Now, when you turn the jar
over, you can slide the card out and the surface tension
across the screen is enough to hold the
entire jar of water up, but it’s still open. I can stick some
needles into the screen, and the surface tension
still holds the water. [WATER SPILLING] [EXCLAIMING AND LAUGHING] I love this one. Take a paper clip or a pen
spring, and balance it gently on the surface of the water. And if it doesn’t work, you can
always try with tissue paper. Oh, see? There we go. Place a bit of tissue paper
on the surface of the water and move the tissue paper out
from under the paper clip. OK. I’m going to take a little bit
of soap on the end of a Q-tip. And if I touch the water with
the end that doesn’t have soap, nothing happens
to the paperclip. But I’m going to touch
the surface with the soap, and watch what happens. It immediately falls. Kind of surprising. [SOUND EFFECTS PLAYING] This one’s pretty easy. See how many drops of water
you can fit on a penny. The number may surprise you. Oh. [MUSIC PLAYING] Aw. [SOUND EFFECTS PLAYING] This is a bonus experiment
and involves a little bit more than surface tension
and should also involves some adult supervision. So as the pan heats up and
I drop some water droplets into it, water droplets that hit
the hot surface will vaporize quicker and quicker until,
eventually, they won’t. And you can see the perfect
little spheres they make. If I keep adding more water,
though, something strange happens. Who knew there was so
much fun science in H20? [MUSIC PLAYING] [ROOSTER CROWING] Chickens. Science. [ROOSTER CROWING] [GIGGLING]
