Here's a thought which could work out especially well with wood. Something I've thought of but never had the brainstorm until now.
I think there'd be some interest in one that had a hole drilled the length (small on the 'internal' end) and sleeved with tubing that could be attached to a liquid holder (balloon etc?) and squirted at the proper moment.
That would be a huge hit here ! Something about that rush of liquid (hot or cold depending)................
