To do this combine groups of 3 toothpicks in parallel in order to make a stronger member. Now the rigid center needs to be created this is where the egg will sit. Repeat steps 1-11 so that two of the figures above exist. Put a pick on each pick from the previous step in parallel and place a dab of glue at the place where the two tips meet. The upward picks should be perpendicular to the grid.Įvery upward extending toothpick, except for the one in the very center then needs to be extended one more pick up. The toothpicks should be oriented so that every angle in the figure is 90 degrees. Next build in the upward direction by attaching one toothpick with a dab of glue to every joint on one side of the grid. ![]() Next select 4 toothpicks and complete the 4x4 grid by connecting them perpendicularly to the joints made in the previous step with a dab of glue. Repeat step 6 on the other 4x1 so the same shape is created.Ĭonnect the two 4x2 pieces by lining up the open ends of each shape in parallel and joining each intersection with a dab of glue. Select one of the long sides of the 4x1 shape and attach one tooth pick aiming away from the structure to each joint using a dab of glue. Repeat steps 1-4 so that another one of these shapes is created. Connect two more “U’s” in parallel using the hot glue. Select three toothpicks then create a “U” shape, essentially the same figure as before, except one side will be removed, then dab a small portion of glue at each vertex.īegin with the square shape, then attach a “U” to one side with glue at the two vertexes. Once satisfied with the general shape dab a small portion of glue at each vertex. Select four toothpicks then create a square with them by lining up each end at a right angle and making sure each of the two opposite sides are parallel. Also,īlowing on joints as they're drying generally does more harm than good by shifting the toothpicks away from the joint. ![]() NOTE: Make your glue joints in the crush structure strong enough to hold together, but not so strong that they will not break during landing. We surmised that this outer shell would deform on impact and absorb kinetic energy, as well as lengthen the decelerationĭistance of the egg and thereby reduce the force on it during landing. We opted for a device with the attributes we had identified as best during testing: a solid, diamond-shaped inner structure, a weak crushable outer shell,Īnd thin spikes on the outside.
