Pogo-Copter (1969)
Take a standard pogo stick, add a wheel and a propeller and what have you got? A spring-loaded ticket to the hospital. As you bounce, the copter's blades send you high into the air. It's like floating on a cloud ? for about a second. Then you crash.
Helmet-Mounted Pistol (1953)
Essentially a hard hat with a gun strapped to the top, this weapon is perfect for the multitasking hunter (or armless serial killer). To shoot, simply blow into the connected tube. Talk about a killer hands-free device.
High-Speed Track Trainer (1982)
No pain, no gain. Supercharge your workout routine with this two-wheeled cart that hitches to the back of a car. As a partner drives, you train by holding on, running, and generally trying not to fall and kill yourself.
