This experiment is so cool, it will blow you away! Easy and simple science experiments for kids to do at home!!! Fun Educational video for kids with The Wild Adventure Girls. Heres the classic experiment: Fill one of the plastic soda bottles 3/4 full with water. Use the Tornado Tube connector to attach the second bottle. Swirl the liquid in the bottle to create a tornado-like funnel as the water moves from the upper to the lower bottle. Its best to use small plastic soda bottles (16 or 20 oz for younger children).
