Type in your ideas below:

Part 1: Establish a testing procedure 1. Set up the empty carton in the middle of the container with sand. DO NOT press carton into the sand.

2. Use the level to establish that the carton is level on the surface of the sand. 3. Using a pair of scissors, lightly tap midway up the plastic container (around the 24oz. mark) with consistent pressure, about 4 taps per second. Continue tapping for 20 seconds. 4. Container should be kept in one place (by partners hand?) to keep it from moving off the table while tapping.

Part 2: Design, Test and Reiterate Design: Using one piece of aluminum foil and two popsicle sticks, modify the building. Wrap the two popsicle sticks, one on each edge (lengthwise), in aluminum foil. Wrap by folding aluminum foil over once. Embed the aluminum foil/popsicle stick modification into the middle of the sand in container. Place carton on top. Check again that the carton is level.
