The hypothesis is that a Solar Furnace can generate temperatures high enough to melt steel.

You will need to make or buy a large number of mirror chips of glass or plastic, each one about 2cm or 3cm in size. You will also need a sheet of plywood and a big bag of screws. You will need to cut up some Post-it notes and lay out and drill the holes as shown. You will need to make "hinges" by cutting a number of round wooden toothpicks into 1/8in segments and place a small dollop of silicone sealant at the corner position of a mirror.

You will need mirror chips of glass or plastic, a sheet of plywood, a big bag of screws, Post-it notes, round wooden toothpicks, and silicone sealant.

After following the steps outlined in this project, you can build a Solar Furnace that can generate temperatures high enough to melt steel. This is an incredibly powerful device, and it is important to remember to keep it covered when not in use, as it can start a fire if left in the sun.

This science project is so interesting and unique because it allows you to build a device that can generate temperatures high enough to melt steel!

Experiment variations to consider include increasing the size of the array and using thicker plywood to prevent warping.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
