This water balloon parachute is one of the best outdoor science experiments for kids on a sunny day. Materials needed: Small water balloons and thin plastic supermarket bags with handles.

Instead, it crashed when the parachute collapsed on the balloon. Undeterred, the 12-year-old gathered the parachute and balloon and placed her experiment on a table. Clark pulled at the plastic.

Students attached plastic trash bags to act as parachutes to slow the egg's fall. Elizabeth O'Leary, a high school junior and designer of one of the landers, told KSBY she enjoyed the experiment.
