You don't need a pool to have your own amazing water race at home. All you need are a few materials from around the house.
* Wax paper
STEP 1: Draw a maze on a piece of paper. Draw a circle at the start of your maze.
STEP 2: Tape a piece of wax paper on top of the maze.
STEP 3: Place a drop of water on the wax paper inside the circle. Using the toothpick, pull the water drop through the maze.
Cohesion causes the water molecules to attract each other. This allows you to move the drop of water through the maze.
