Kindergarten Science Week

For Kindergarten Science Week, Connor and his assistant (Daddy) launched Alka Seltzer rockets for his class.  He used a small plastic tube filled with water.  Then he poured Alka Seltzer into the tube before closing it off with a cork and shaking it a bit.  When the pressure built up in the tube, the cork popped out and shot the rocket up a few feet.  We determined that the less water in the tube, the higher the rocket will shoot up.
