Brief Description: A simple, yet challenging puzzle requiring the chimps to untie and pull apart frozen fabric to get to their treats.
Materials: Pieces of fabric large enough to tie into knots and able to absorb water. We use towels and blankets.
Assembly instructions: Cut pieces of blanket or towels to make your fabric pieces. Any size will work as long as you are able to tie a knot in them.
How to use: Dip fabric pieces in water. Towels will absorb more water and make more difficult knots to untie when they freeze. Put nuts or other treats in the middle of the fabric piece and tie into a knot. Freeze on a cookie sheet.
Price: No cost if using recycled fabric
