Discussion Questions: Columns: Experimenting with Balloons
Describe the forces at play when the balloons are supporting the weight of the boy. Why do you think the water balloon supported the boy's weight better than air did? Did the ZOOM cast members investigate the differences between air and water in a systematic way? Have you noticed the flat place where a car tire touches the road? Do you think the size of that flat place depends on the air pressure in the tire? Was there more pressure in the water or in the air in these balloons?
