Jenga is a pretty simple game… that gets a wee bit trickier when you can’t use your hands. In particular playing with tongs to handle the dry ice means that if you squeeze too hard the dry ice will squeal as it sublimates under the tongs and the tongs move as you squeeze and the gas escapes. It just seems to make people more nervous, but it looks cool – especially if you add blinking LEDs. Using a mitre saw with a simple jig is a good way to turn out uniform pieces in short order.
