Directions for Unpredictable Earthquakes

Materials- plywood, Styrofoam insulation, 80 grit sandpaper, screws, drywall, flexible plastic tubing (exercise band), duct tape, glue, 2 inch by 0.5 inch boards, paint

Cost- about $40

1. Cut plywood board into 3 by 1.5 foot section. Glue sandpaper over the surface of half of the plywood. Screw the corners of the sandpaper down as well.
2. Cut drywall into one 1.5 by 0.75 foot section and one 1.5 by 1.5 foot section. 
3. Screw the larger piece of drywall over the half of the plywood board without the sandpaper.
4. Drill two sets of screws into the smaller piece of drywall. Make sure the sets of screws line up in the center of the drywall. Both sets should be equal distance from the long end of the drywall. Wrap a section of flexible tubing in between both sets of screws so the tubing runs from one set to the other with excess on both ends. Then place duct tape over the tubing to secure it to the drywall. 
5. Cut a 1.5 by 0.75 piece of Styrofoam. Create a “channel” down the center of the foam so that it will fit over the duct tape and tubing. 
6. Glue the Styrofoam over the smaller section of drywall with the tubing. 
7. Create a border out of 2 by 0.5 boards around the large plywood base. Glue the border to the plywood.
8. Place the drywall/Styrofoam with the tubing onto of the plywood with sandpaper. Allow the tubing to hang over the edges of the border. Paint both the attached drywall and the unattached piece with the tubing. 


Directions for Engineering for Disaster

Materials- 12 rubber bands, plywood, 2 inch by 4 inch boards, screws, small pen springs, poster board, duct tape, wood glue, paint

Cost- about $40
1. Cut a piece of board or plywood into a 12” square. On the underside of the plywood, place four screws at each corner but do not screw them down completely. Leave about 0.5 inch of the screw showing. 
2. Cut four sections of 2 foot long 2” by 4”s. 
3. Construct a square frame out of 2” x 4”s that fits around the wood square. Make sure the 2” x 4”s are oriented so that the frame is 4” high. 
4. Mount wood screws on the top edge of the frame at each of the corners. Don’t screw in the screws all the way. 
5. Loop three rubber bands around each pair of screws so that the plywood square is suspended like a trampoline within the frame. 
6. Repeat steps 1 through 5 to make a second frame. 
7. Build two identical rectangular buildings out of tag board that have a 5 in. by 5 in. base and are 10 in. high. 
8. On the top side of one of the plywood squares draw a 5 in. by 5 in. square in the center of the plywood. Arrange 5 small springs in this square and glue them down.
9. Cut out two 5 in. by 5 in. plywood squares. Place one of these on top of the springs and glue it to them.
10. Attach each of the buildings to a 5 in. by 5 in. plywood piece. Paint the buildings.
11. Paint the 12 in. by 12 in. plywood piece green and the frame white.
