You have to drink soda pretty fast so it doesn’t go flat, right? Not anymore. Not everyone can finish the can. It’s either drink the flat beverage or be wasteful. Ukranian inventor Johan De Broyer is a man with a love of carbonated beverages and a dream. He has come up with a neat way to re-seal cans.

His idea opens up new possibilities in advertising too. You pop the top as usual, then when you want to re-seal it, just turn the pop top tab and it completely closes up the can. That wouldn’t mean squat if it were just an enclosure, but Johan claims his invention can create a completely gas-tight and liquid-tight seal. Advertisers should love the fact that they can take advantage of the resealed top.

A former sheepherder and current rocket scientist/inventor Jem Stansfield, took a couple of air canisters that are typically used by firefighters for their breathing gear, and strapped them on a moped. The result is an air-powered bike that spits out cleaner exhaust then the air that it initially takes in.

Both compressed air cylinders drive a pair of rotary air engines that propel the bike to a top speed of 18mph. It will only go about 7 miles until more air is required. Lucky for him, he has a local dive shop where he can fill up and he’s good to go. It’s people like this that tick off the oil companies, which I find awesome.
