If you can't wrap the stone in foil, don’t worry. Just use a smaller stone.

No! It’s okay if you used more hexamethylenetetramine than indicated in the instructions. Feel free to keep going.

Note that the first step is to cut a sheet of foil in half!

If you look closely, you’ll notice that the foil from the set is much thicker than ordinary foil. You can try using 3-4 layers of ordinary aluminum foil for the same approximate result.

This can happen if the stone is too big. Try using a smaller stone.

Be sure to use a new piece of foil too!
