As we look at Simple Machines in Science I would like to put forth the challenge:
Who can design & create the most innovative, creative, efficient egg cracker?
Task: As teams make an egg cracker with a system of at least 4 simple machines. You can have one person start it, but it must run by itself after that until it cracks the egg.
For ideas and specific requirements see the link below. The rules are on pg 5 of the linked PDF file. All rules apply except #3. Use as many interesting materials and simple machines as you can. Have fun!
