For those with dc who love to tinker, a fun project

[Ms. Riding Hood]

This is a cool web page published by Stephen F. Austin State University, in Nacogdoches, TX, on building a Stirling engine (http://www.physics.sfasu.edu/astro/courses/egr112/StirlingEngine/stirling.html). It's has clear, easy to follow instructions, with video resources and a very simple supply list--mostly things you have sitting around the house.
