The Museum of Questionable Medical Devices has actual working versions of many of these devices. Many of these devices were siezed by the US FDA as they were deemed harmful or plain did not provide any benefits. I'll let you figure out what device is pictured
We generally found this museum not as interesting as the Science Museum. The displays seemed to be organized randomly and were difficult to figure out. They almost need a huckster there trying to cure you or stop your aging, etc. etc. Also the day we went, it did not open until 5pm. So we actually had to travel to the museum twice to see it.
Location: 201 Main St. S.E., Minneapolis, Minnesota (the area is cool - the Historic St. Anthony area)

The Minnesota Renaissance Festival runs in late summer, and is a fun way to spend a weekend afternoon. There is 12 stages with shows running all day, so it's hard to catch all the live acts. The food is plentiful, and shops are everywhere. Try and catch Puke & Snot, a live comedy act, who are quite popular. There is also live jousts, kiddie rides, and other activities.
