Rubik's cubes are a blast to solve and are not nearly has hard as you might think. When they were invented the 1970's, people would get frustrated and tear the stickers off and rearranging them. You don't have to do that! Below you will find a guide that was put together by an organization called YouCanDotheCube (youcandothecube.com). The first three steps are the hardest, so stick with it. We have had so much fun and success solving cubes we've even made it on the news.
Hexastix is a cool sculpture you can make with 72 pencils. It is not nearly as hard to make as it looks. All you need is 72 pencils, 8 rubber bands, and about an hour. The sculpture was originally created by George Hart. You can check out his work here. Just like nearly everything else, there are people who have expertise and are willing to share it freely on the internet. Just Google, “How to build a hexastix?” If you can’t find a video you like, here are a couple of good ones: Matt Parker & Frederick Nicholas. (If you haven’t checked out Matt Parker’s “Standup Maths” channel, you’re missing out; he’s brilliant, he’s hilarious, and he’s British...so it's okay that he says "maths" instead of "math".)
