The Collapsing Can
Did you know you can crush a can by using air? It's another experiment that might get
you and your family "Hooked on Science."
Ingredients
Instructions
STEP 1 : Fill the bowl with ice and water.
STEP 2 : Place 1 tablespoon of water into the empty soda can. Turn the hot plate on highand place the soda can on the hot plate.
STEP 3 : Once the water vapor appears above the can use the tongs and grasp the can.
STEP 4: QUICKLY flip the can and dip the can into the cold water.
Explanation
You removed the air from inside the can by heating the water and then dipping the can
into the icy water. Once the air is removed the air on the outside is so strong it crushes
the can.

Noisy Money
Did you know you could create some strange sounds by using an assortment of coins and a
balloon?
Ingredients
Instructions
STEP 1: Push a coin through the small opening of the balloon.
STEP 2: Blow up the balloon and tie off the opening.
STEP 3: Place the tied off part of the balloon in the palm of your right hand, squeeze the balloon, and then move your hand in a circular motion.
Explanation
The unique shape of the coin vibrated the walls of the balloon creating the strange noise.

Cup of Sounds
Did you know you can create unique sounds by using some ingredients from around the
house.
Ingredients
Instructions
STEP 1: Using a knife, create a hole in the bottom of the plastic cup.
STEP 2: Cut about 2 feet of string and thread the string through the hole in the plastic cup.
STEP 3: Tie a knot in the string big enough so the string will not pull out of the hole in the plastic cup.
STEP 4: Wet the sponge, grab the string close to the plastic cup, and then pull downward.
Explanation
You created sound by moving the wet sponge along the string. The sound was amplified as
it passed through the plastic cup.

Soaring Toilet Paper
Did you know a leaf blower can be used to rapidly unroll an entire roll of toilet Paper?
Outreach Science Educator Jason Lindsey tells you the cool science behind this awesome
experiment.
Ingredients
Instructions
STEP 1 : Place the toilet paper on the dowel and unroll the tissue.
STEP 2 : Hold the dowel horizontally with the roll unrolling away from you.
STEP 3: Turn on the leaf blower and aim the stream of air just over the top surface of the roll.
Explanation
Bernoulli's Principle states that the pressure of a liquid decreases as its velocity increases.
Increasing the velocity over the surface of the paper, lowers the pressure of the air pushing
on the toilet paper. The paper is lifted because there is a sufficient number of air molecules
striking the lower side of the toilet paper to overcome the downward pull of gravity and the
lower air pressure on the upper side.

Diaper Genie Windbag
How many breaths of air will it take you to blow up a six foot long Diaper Genie windbag?
Using Bernoulli's Principle it will only take one breath. Here's another experiment that might
get you "Hooked on Science."
Ingredients
Instructions
STEP 1: Remove about six feet of Diaper Genie refill and cut.
STEP 2: Tie a knot in one end of Diaper Genie windbag.
STEP 3: Using two fingers and two thumbs hold open the end of the bag that is not tied.
STEP 4: Holding the bag six to twelve inches from your mouth and blow a stream of air into the bag.
Explanation
As the stream of air from your mouth blows into the bag it pulls more air from the
atmosphere into the Diaper Genie bag creating a super breath.

Tablecloth Science Trick
Here's an experiment you can try after Thanksgiving dinner that might get the entire family
"Hooked on Science."
Ingredients
Instructions
STEP 1: Place the tablecloth on the table and then arrange the glass dishes on the tablecloth.
STEP 2: Grab the edges of the tablecloth and pull down toward the floor quickly.
Explanation
The dishes stayed as you quickly removed the tablecloth because of inertia. Inertia
describes how all objects tend to resist change in motion.

Rocket Balloon
They whine and buzz while flying through the air and at the same time Rocket Balloons
teach kids a science lesson they won’t forget.
Ingredients
Instructions
STEP 1: Using the hand pump inflate the Rocket Balloon.
STEP 2: Hold the end of the Rocket Balloon so the air doesn’t escape from the Rocket Balloon.
STEP 3: Pointing the Rocket Balloon away from your face and others release the Rocket
Balloon.
Explanation
The air rushing out of the balloon forces the Rocket Balloon through the air. This
experiment is perfect for teaching Newton’s Laws of Motion.

| Newton’s First Law of Motion – Newton’s First Law of Motion states that the | |
| velocity of an object can be changed only if an unbalanced force is applied to it. | ||
| Newton’s First Second Law of Motion – Newton’s Second Law of Motion states | |
| that acceleration is produced when a force acts on a mass, and the greater the mass of an object, the greater the force needed to accelerate it. | ||
| Newton’s Third Law of Motion – Newton’s Third Law of Motion states that for every | |
| action there is a reaction equal in strength and opposite in direction. |
