If regular ol’ skateboarding isn’t challenging enough for your little daredevil, maybe she should give branch boarding a try. The folks at Tree of Motion have been experimenting with the idea of mounting skateboard trucks and wheels to an actual tree branch for the past six years on a small scale, and now they want to open up this upcycled form of transportation to the masses. They offer handy step-by-step directions for building your very own BranchBoard on their website — and they also have a Facebook page to get people discussing green design and the groovy feeling you get from taking this natural ride out for a spin. Just make sure your little Tony Hawk wannabe doesn’t cut down any branches to make her board — there are plenty of fallen specimens around to use! What a cool way to cruise back to school.
