For those who don't measure, follow instructions and like to fly by the seat of your pants. This Instructable is like mixing cookie batter. I originally created this to make the mold for a plastic ant farm.
Step 1: Materials You Will Need
You need to gather the following items.
1. Plaster Paris (can get at any hobby store, hardware store, etc)
2. A Bucket (I like to use kitty litter buckets because the come with lids)
3. A plastic cup
4. A stick to mix things
5. A messy place to lay things down.
