This is a favorite among kids:

You’ll need:

• string or yarn
• large beads or buttons
• ice tray
• water
• time, prepare ahead of time (kids hate to wait!)

String the beads, and arrange so that each bead sits in a cavity in the tray. Add water, don’t overfill. Freeze.

When frozen remove and tie around your neck. Ahhh.
