Inhaling helium as a science trick is very much 1980s; what you really need to do is try inhaling an inert gas with a little more density, as they did on Rough Science recently.
Rough Science is a momentary and randomly produced vodcast from Australian science educator Sean M. Elliott. He is all kinds of fun and mayhem for students, but has that great knack of being a good mix of geek dad humor and renegade science type (watch him go to town on the periodic table in the above episode).
The episode above is the most recent: Sean explains very simply the difference between inhaling different inert gases and why that changes the sound of our voice. Check out what happens when you inhale xenon.
Sean performs Rough Science as a stage show, but I’m looking forward to more vodcasts from him in coming months. You canfollow him on Twitter for announcements.
Find out more about the science educational ramblings of Sean at Theoretikos. He also has a great little podcast running at the moment on all things space called LaunchPod.
