Humans have been inventing things since the dawn of civilization. Some inventions, like electricity and the internet, have become things we cannot live without. But not every idea that made it off the drawing board was a good one. Below is a collection of silly and pointless creations — from a family bicycle complete with a sewing machine and table, to a two-sided mirror brush on long sticks — that prove not every invention deserves to exist.

Back in 1948, there was apparently nothing weird about riding across a lake on a motorized surfboard while wearing a nice suit and bowler hat and smoking a cigarette. Forget his lack of safety gear — inventor Joe Gilpin looks cool gliding along on the water.

Inventor John H. T. Rinfret demonstrates his anti-bandit bag. To foil thieves, a chain is pulled and the bottom of the case falls out so the contents are scattered over the floor. That’ll stop those thieves from getting at the contents of your bag! No, wait. It won’t.

This shower hood from 1970 has us baffled. Is it meant to keep your head dry while you shower? Or does it let you just wash your hair while your face stays dry?

A machine to measure the shape of your head. The machine consisted of 1,954 parts in a metal carrier with a continuous motor-driven belt inside a walnut cabinet containing statements about 32 mental faculties. These faculties were each rated 1 through 5, “deficient” to “very superior,” so that there were 160 possible statements but an almost unlimited number of possible combinations.

In the 1950s, everyone smoked. In fact, they couldn’t smoke fast enough, if this cigarette pack holder is any indication. Did the inventor of this contraption not know that excess nicotine causes violent vomiting, dizziness, and severe headache?

In the 1920s, Hugo Gernsback published a design for a creepy-looking helmet that blocks out sound and vision so someone can focus on their work.
