[this is school]

Today, Anja, Cece, and I did the heat shields lab. We had a wooden dowel that had a nail glued onto it and we had to make a heat shield to keep the glue from melting for as long as possible. We were given a piece of wire netting, a large piece of aluminum foil, a washer, and a bolt. My design was in this order, stacked from closest to glue, to farthest from glue: wire netting, washer, aluminum foil, bolt.. and a small piece of aluminum to cover the tip of the screw. The other thing I did was designed it so the wire netting made a sort of a dome shape, and the aluminum on top made a bowl shape.. it looked like this: )( )=netting and (=foil I thought the aluminum could then reflect the heat and protect the metal for longer, while the under lair curved the opposite way to act like a dome, and also allow the heat that made it through the aluminum to spread out and not give direct heat to the glue. I was only to test my shield once, but it was able to last for approximately 18 seconds... I was surprised how quickly the heat traveled through the aluminum and how hard it was to make an effective shield. I was also surprised by how many different ways you could make the shield and how many different varieties and combinations there were.
