DIY Aqua chopper! Krack made this aqua chopper by attaching some barrels to his old bicycle and often rode it with pride. And why not, cuz – it is easy to use, no training or license is needed, and moreover, it will not cost you the earth. Just take it to the nearest water reservoir, and peddle to make it go. Perhaps, Krackâs the best man knowing about the safety factor, rest assured â must be fun riding this! Need a change? Then go get some barrels and enjoy the ride.
