Its coming to summer soon. Its going to be 90 degrees on wednsday. i wanted to make those collars that have the little beads that expand when soaked in water. But I don't know the name or where to get the beads. Can anyone please help?
I think what you are looking for is polymer cyrstals. you can get them at Walmart like Momo said or check online a lot of candle suppliers have them to make those smelly Jellies in a jar.
