Color Changing When You Spin It
A while back I had a glasses case that would rotate colors when you spun it around. For years, that little case would distract me (and all of my classmates) during Algebra. However, I never saw another case like that nor any other accessory in the following years.
Until today. These nifty little pen/calculator sets come in the exact same type of container, but smaller and more convenient. The Illusion Series brand also puts out business card holders, paper clip containers and sewing kits that work the same way. Now the next generation will have ample distraction during math- an essential to growing up.
