Mix clean sand and white craft glue to obtain an oatmeal type of consistency (add small spoonfuls of water but no more than two). Clean sand can be obtained from a beach or at a craft store. Blow up a balloon or a beach ball (we had more success with a beach ball as the balloon if too tight can pop while doing this) and rest the tied end into a bowl. Start at the top and pour the liquid and allow to run down. Make sure there are no gaps – you do not want a spider web effect. Dripping is allowed. Allow to dry overnight. Repeat process to create a thick three or four layer effect. Now on the last layer you will watch for it to be almost hard – then you will flip it out over to rest on what used to be the top. You are going to do this to create a flat bottom. Too early this will form in a huge puddle – too late and it won’t form. Its cheap and that is good because if you mess up try again.
That is such a cool bowl! How much sand and glue should one start out with?
This really depends on how big you want your bowl. For a salad sized bowl start with one cup sand and add glue until the desired consistency is acquired which is like oatmeal. If you try it send pics and I’ll be glad to post them! Good luck and have lots of fun!
