Thermite
Procedure
- Mix 50-55g ferric oxide powder with 15g Al powder.
- Get 2 red clay flower pots, one inside the other. Put a piece of filter
paper at the bottom of the pot, pour thermite mix into the pot.
- Put the pots on a ring stand behind a safety shield. Also have a large
sand bath placed below the pots in order to catch the liquid metal when
it drops through the pots.
- Insert Mg fuse, light fuse with a butane lighter, step back and watch
the show.
- If the Mg fuse is a dud, light the thermite mix with the propane hand
torch.
