What can we do with this?

Take one engineering summer camp

Enroll 7 boys

Buy a roll of tin foil

Experiment 1:

Place tin foil pieces on the table and give no rules


No Rules Tin FoilTin Foil Ball

Be surprised that 6 boys did nothing.  One made a ball.

Experiment 2:

Assign engineering challenge: Build a solar oven


Much tin foil was used.  Some effectively, some not so much.  But fun was had.  Success!
