Twig Raft
Winston and I made a twig raft using the branches from the apple tree. Amazingly the raft floated. Winston tested it with his small cars and kept trying to get his big cars to float. He now has discovered that his big cars can float in his big sail boat.
By the way, the best way is to add three horizontal twigs to keep the vertical twigs from moving and rope is better than ribbon.
His big rig carried the the left over twigs.
