Rub a dub dub, there's a science lab in the tub!

Stick the four orange suction cup rings to the bathtub wall, placing one above the other. Attach the plastic funnel shapes to the three colorful patterned reservoirs placing each, as well as the water wheel, into the orange rings. Use the blue beaker to pour in the water and observe. Do they all drip in the same way? Does the water wheel spin fast or slow? Rearrange the order to get different results. Bubbles are optional.
