lidyou will need: tape (scotch perferred) a stainless steel or alluminum nail plastic or glass jar a lid some wire alluminum foil salt water
Step 2: Foil it up
tear out a piece of foil so that it can stretch all the way around the jar. cut off any foil that comes off of the the edges of the jar, and smooth it flat. The less wrinkles, the better. If there are any tears, remove the foild and put on a new sheet. If you cannot, or are too lazy to, cut out a small square of foil that is big enough to cover the hole and cover it completely with tape. Place the taped foil over the hole. make sure that there are no sharp points on the foil, aand never add more than one layer to the foil.
Step 3: Prep the lid
use a drill to bore a hole through the lid of the jar. then place the nail in the hole so that it goes down deep enough so it will touch the water with the jar is filled. the head of the nail should not touch the lid. the nail should fit snuggly in the hole, but if not, use hot glue to keep it in place.
