Smarties

After a couple of hours karate training this evening, and a meal, we settled down to an older cooperative game Sauerbaum (Acid Tree) where the players - by means not explained - run around the branches of a diamond-branched tree, hoovering up the acidic raindrops before they get to the roots.

Hmm, now I come to explain the theme I start to wonder whether 'acid' actually refers to the rain or the designer's creative chemistry of choice...
