How to

6 cups of cold water

Make sure it's cold water

It shows 1 minute, but mix for 1 min 30 sec

It's going to be lumpy, keep mixing

Making sure hand is coated and not touching the sides/bottom

Mold is firm, suction broken

I'm free

Material peels right off

I like to clean the edges

1 & 2/3 cups of cold water

Get all the lumps out!  Make it smooth

Make sure to bang out the air bubbles along the way

I filled it passed the opening; gives cast a base

Wash plaster off in a bucket or outside with a hose - it'll clog your pipes

3 hours later, all firmed up

Make some cuts, tear off some pieces

There it is!

See the base I got from overfilling the mold
