First they did a germ spread simulation.
Each shared half their container's contents with 2 others.
Most stared out with flour. Two had baking soda.
At the end each container was tested with vinegar.
Then they tried to figure out who had the "germs" in the beginning.
This is a good FLL Food Factor exercise.
Then they went outside to get the containers to blast up in the air.
Meanwhile the solar panels were connected to capacitors that were then
saving up electricity.
The containers did best with baking soda and viniger.
