Science
in the Blink of an Eye
By Deborah Shelton
Help children develop a love for science or nurture their already
growing interest with these simple experiments.
Cloud maker
Ever wanted to catch a cloud in a bottle? Now's your chance! Pour
just a splash of water into a two-liter plastic bottle. Light
a match (a grownup's job) and drop it into the bottle. Immediately
replace the lid and squeeze the bottle a few times to watch your
cloud form.
Magic flowers
Create your own unique flowers with this neat trick. Fill a vase
with water and eight to 10 drops of food coloring. Cut the stem
of a white carnation at a diagonal and place the flower into the
vase. After a few hours, you will notice a slight change of color
in the petals. Let the flower soak overnight and observe the dramatic
change in the morning.
Mouth lightning
Don't worry -- this doesn't hurt a bit! In fact, you may want
to try this at your next sleepover party. Stand in front of a
mirror and turn off all of the lights. Pop a wintergreen-flavored
Life Saver™ into your mouth and chew. Can you believe your
eyes? This "lightning" phenomenon is called triboluminescence.
