The pogo stick. One of the most frustrating toys of my childhood for sure. On the other hand, once you started jumping and got the hang of it, it provided endless fun during the summer. Check out the Flybar, a modern update on the pogo stick. Using super-strong elastic bands and an adjustable piston, you can get some serious height on this stick. We’re talking over 7 feet high, ensuring that you can hop over cars, humans and dog shit alike. Flybar doesn’t come cheap though. Look to shell out $210 in the US and $320 in the UK.
