Supplies: Jar, String, 2 Cups of Sugar, 1/4 Cup Hot Water.
What happens: Fill the jar with the hot water. Add the sugar and stir until most of it is dissolved.
(the heat helps the water dissolve the sugar). Hang the string in the jar (try to keep it off the
bottom). Close the lid to keep the string in place. Put the jar in a warm place (outside or a window
sill). Check it everyday until you have some sugar crystals. (a few days should work).
Floating Miniature Milkyway
Supplies: 1 or 2 Liter plastic soda bottle. Miniature milky way individually sealed.
What happens: For this experiment you will need a candy that just barely floats. (test it by putting it
into a bowl of water and find one that barely floats). Take a packet that barely floats and put it in
the clear plastic bottle. Fill the bottle to the brim with water and screw the cap on tight. Squeeze
the sides of the bottle. What happens?
Explanation: The packet or candy has a small bubble of air trapped in it. When you squeeze the
outside of the bottle, you increase the pressure inside the bottle. This will compress the air inside
the packet, which changes the overall density of the packet. When the air is compressed enough,
the density of the packet will be greater than the density of the water in the bottle, and the packet
will sink. When you release the pressure on the outside of the bottle, the air in the packet will
expand, increasing the buoyancy of the packet, and the packet will rise to the top.
Candy Fountain Explosion
Next time you're at the grocery store pick up
some Mentos Candy and a 2 Liter of soda. Next
take a rolled up tube and drop all the Mentos
inside. (Place a playing card under the tube to
keep the Mentos from falling out...whoops too
late!) Now put on your safety goggles (or sun
glasses). Remove the cap from the bottle and
quickly drop in all the Mentos at once.
Quickly step back and watch the fountain erupt
everywhere! You can drink the soda when it's
Bubble Gum Fun
Have you ever gotten in trouble for chewing gum? Now you can tell your teacher that chewing gum
has all kinds of benefits including: helping you stay focused...to losing weight! Check out Wrigley's
Bubble Gum Research: Wrigley.com
You can also create a Bubble Gum Science Project by
comparing Bubble Gum Brands and testing (that's the
best part) different kinds. Measure how big you can blow
bubbles, which is stickier, and which flavor lasts the longest.
Is it possible to repair a flat tire with gum??
Ice Cream From a Squishy Bag
Squeeze your way to an ice cream headache~ it's worth it!
Here's what you need:
1/2 cup milk
1/2 teaspoon vanilla
1 tablespoon sugar
4 cups crushed ice
4 tablespoons salt
2 quart size Zip-loc bags
1 gallon size Zip-loc freezer bag
Gloves are great for keeping your hands warm while you make it.
Combine the milk, vanilla and sugar into one of the quart size bags. Seal tightly - squeezing out
as much air as possible. Too much air left inside may force the bag open during shaking. Place
this bag inside the other quart size bag, again leaving as little air inside as possible and sealing
well. By double-bagging, the risk of salt and ice leaking into the ice cream is reduced. Put the two
bags inside the gallon size bag and fill the bag with ice, then sprinkle salt on top. Again let all the
air escape and seal the bag. Wear your gloves (if you want) and shake and massage the bag,
making sure the ice surrounds the cream mixture.
Wait for the bag to say, "Ahhhhhh, I'm very relaxed now" or simply wait 5 to 10 minutes for the
mixture to freeze into ice cream. Now eat, eat, eat!
Lightning in Your Mouth
Turn out the lights and allow your eyes to become accustomed to the dark. Then, while looking into
a mirror, pop a wintergreen Life Saver into your mouth and chew. Charge separation is produced
as the candy fragments, and the discharge produces light. This phenomenon is called
triboluminescence and can be observed with other flavors of hard candy (even sugar cubes) but
wintergreen flavor seems to work best.
