2. Supplies… Plywood 3 screws 3 Jenga blocks 1 Styrofoam cup Fishing line
Empty Playdo can
with 5.50 in dimes
A hammer
1 sad egg
A funnel
A bowl

3. Diagram Overview Kinetic Energy of rope pulling hammer
Energy Loss of perfectly inelastic collision
Kinetic Energy of trigger
Gravitational Energy of falling weight
Gravitational Energy of the domino fall
Kinetic Energy of rope pulling out board
Gravitational Energy of the cup falling

4. Alterations to Original Design
Added Jenga to cup
Added weight and momentum
Cut portion out of backing
Was creating drag
Switched to a larger screw
Gave hammer more room to swing

5. Energy Lost / Efficiency
When the hammer collides with the Egg
ft-lbs
Our Efficiency
.75%
So as you can see, there are better ways to crack an egg, but this has a hammer involved !!
