In light of the school closures most of us are experiencing right now I would imagine i'm not the only one looking for something to occupy my kids. I have 2 boys, 14 & 12, and I would love to find some kind of mechanical project to keep them busy and teach them a thing or two. I won't always be able to lend a hand so it needs to be something they can work on without me at least some of the time. One thought I had was to order one of those kits to add a 2 stroke engine to a bicycle. I like the fact it comes with everything you need and the boys could probably find some direction online when they get stuck on something. The kit is at the top of what i'd be willing to spend but before pulling the trigger on that i'd like to know what other suggestions you all would have. What say you?
