STEP 2:
You also need to make the natron for the SimMummies before you plan on mummifying them.

 

WHAT YOU WILL NEED:

per student...
2 boxes (1 lb) of baking soda
2 canisters (1 lb 10 oz) of salt
per class...
1 large plastic tub

 

PROCEDURE:

1. Mix the salt and baking soda together in a 1:1 ratio.
2. If you have so many students that the tub would over fill, either make half the natron later or get a second plastic tub.
