Sunday, June 6 @ 2 pm RAINBOW PARK!
BUILD A SLANK! (an ice sled!)
Wash tub or similar container
Fill the tub with 2" of water, then freeze.
Place a trimmed onion bag on top of ice. Fill with another 1" of water and freeze.
(Use small stones to weigh down the bag if it floats. The onion bag acts like rebar that you would find in concrete.)
Place rope on top of ice.
Place another trimmed onion bag on top of rope. Fill 1" of water and freeze.
(Again, use stones for weighting if needed.)
Finally, you can take a small towel, or piece of carpet, and wet it slightly. Place it on top and allow it to freeze to your last layer of ice. This will allow you to sit on the ice block and not slide off.
