Automatic Lotion Dispenser

OUR SCIENCE PROJECT:
THE AUTOMATIC LOTION DISPENSER
By, Clay K and Rudy

We picked our project when we were going through ideas and decided that the lotion dispenser would be the most fun. We were curious to find out if the marble would activate the button on the lotion.
Materials needed: A three foot cardboard tube placed vertically. Attach at the top a vee-shaped piece of cardboard. Attach to that a two foot cardboard tube placed at an angle. A marble about 1-in. in diameter. A lotion bottle with an easy press top.
How it works: First you put the marble down the first tilted tube. Then the marble rolls down to the vee-shaped cardboard. Next the marble falls down the vertical tube. Finally the marble hits the top of the lotion bottle which deposits lotion on your hand.
Benefits: You do not have to press the top of the lotion bottle, but just have to drop a ball into a tube. You will never have rough hands again!
