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 high | | and 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. ________________________________________________________________________
April 16, 2009 Noisy Money Did you know you could create some strange sounds by using an assortment of coins and a balloon?
Ingredients
 | | 3 Transparent Balloon
|  | | Assortment of Coins
|
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. ________________________________________________________________________
March 19, 2009 Cup of Sounds Did you know you can create unique sounds by using some ingredients from around the house.
Ingredients
 | | Plastic Cup
|  | | Sponge
|  | | String
|  | | Water
|
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. ________________________________________________________________________
February 26, 2009 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
 | | Leaf Blower
|  | | Toilet Paper
|  | | Dowel Rod
|
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.

January 15, 2009 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
 | | Diaper Genie Refill
|
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. ________________________________________________________________________
December 12, 2008 Tablecloth Science Trick Here's an experiment you can try after Thanksgiving dinner that might get the entire family "Hooked on Science."
Ingredients
 | | Several Heavy Glass Dishes
|  | | Tablecloth without a Hem
|  | | Square Table with an Edge
|
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. ________________________________________________________________________
November 7, 2008 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
 | | Rocket Balloon
|  | | Hand Pump
|
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.
