Last week we ran the third DCPH® and for one of the puzzles we built a carnival game, Snowball Toss. This puzzle was presented as a rebus painted with thermochromatic paint on a piece of plywood. When warm (above 85℉) both the background and the symbols are white. Teams threw water balloons to cool down the board, revealing the rebus in grey. The trickiest symbol to paint was “bras” which inspired this post.
