Toilet Paper Snow

Want to create your own snow storm? If so, “Science Guy” Jason Lindsey with Hooked on Science says all you need are a few ingredients from around the house.

Ingredients

Leaf Blower

Toilet Paper

Dowel Rod

Water

 

Instructions

STEP 1: Wet one side of the toilet paper with the water.

STEP 2: Place the toilet paper on the dowel rod and unroll a few pieces of tissue.

STEP 3: Hold the dowel rod horizontally so the roll will unroll away from you.

STEP 4: Turn on the leaf blower and aim the stream of air just over the top surface of the toilet paper.

 

Explanation

Bernoulli’s Principle states that the pressure exerted by a fluid decreases as its velocity increases. Increasing the velocity over the top surface of the toilet paper lowers the pressure of the air pushing down on the paper. The paper is lifted because there is now an unbalanced force of air pressure acting upward. The water weakens the toilet paper and causes it to tear into pieces.
