As a courtesy to Facility, each competitor is given a green garbage bag to house the egg contraption. Egg drop is tested from the second floor into the rotunda area at the front of our school. Weights are available throughout the project for testing. All bridges are tested by adding weights hung from the centre of the bridge which itself is suspended between a stack of textbook, usually 20 cm off the bench surface. If they require more supplies, they may trade amongst themselves but nothing comes in from the outside, this is well policed by students. They may also do so after school or at lunch. Students are given an additional five periods to tweak their projects-the last 20 minutes of class. Next block (blocks are uniform at 90 min each) they build. At the end of that block they must present a finished diagram with measurements for approval. load concepts are discussed in the first half of period then they brainstorm for second half.
Students are given a 'kit' containing pasta(300g), hot glue(15 sticks) and mini hot glue guns. Best one so far was a 27 cm long box-style bridge and held weights up to 1.6 kg. Cut the L-shape out of the wood with a saw. The small (horizontal) portion of the L shape should be slightly smaller than the box you carved in the stock. Students have also built bridges which are then hung with weights to test strength. Use a thinner piece (around 1 inch thick) of pine wood to create the trigger system. Tried white glue but the time it takes to dry causes the pasta to soften as well. Popsicle sticks can be glued, taped, or even friction-fit together to create all sorts of cool objects and designs. Students can work in pairs or go at it alone. By Sam DeRose in Living Office Supply Hacks. (less toothpicks, less time to build, increased mass in the bucket, higher drop height.

You can check out the videos on step 4 for a better idea of what happens to the final product! don't bother with the reasons for the experiment and skip to the fun part. If you're a teacher friend, continue reading below. The force being applied to the egg contraption is in the form of a 5 gallon bucket falling from above. The only materials they are allowed to work with are flat wooden toothpicks and wood glue. In this project, students must build a contraption that can protect an egg from being crushed.
