Heat Shield

In class we worked on an expiriment called heat shield. We had a torch, some mesh, some tin foil, nuts, bolts, and sticks with screws glued to the end. We had to make a structure to protect the screw and the glue that kept it on. At first I tried one that was like a flower, but that just funneled the heat to the screw. Then i tried making a ball of tin foil around the screw and then mesh around that (without touching). That worked much better because the heat wasn't going through anything to touch the screw, they were all separet. We learned about convection and cunduction and radiation. Our longest heat shield lasted 4 min. and 12 sec.
