if you want a first time go, then you need to pull out the big guns and use a sparkler, not the cheap sparklers but the big ones.

You've got to get the proportions right (if I recall correctly, it's about 7 parts aluminium powder to one part iron oxide by weight).

The correct mixture is also quite hard to light. If you can get magnesium ribbon, that makes a decent fuse, light the tip with your blow torch, but do not look at the magnesium flame - it gives out enough UV to damage your eyes.

1. You'll put an eye out.
2. Use the top search box and put in "thermite".
