Ooh! Can you believe that you can make these yourself? Well, most of them. All you need is packaging material like the spongy polymer type as seen above, a craft knife, and a steady hand. If you’re a hoarder like me, you can always save anything that is soft, cut-able, yet durable to cut into cuboids, cubes or prisms because you only need straight line cuts for those. For the cylinders, I cut off sections from the ends of my pool noodles. What? A pool noodle does not have to be so long…

As for the spheres, those are the only ones I bought, I got them at a craft store. They sell them to be used to create bouquets, pin cushions and other crafty stuff. I also saw Styrofoam cones too but they were too large. Anyway, it was a fun experience to discover ways of recycling to make solids and they are really quiet to handle in the classroom. That’s an added perk. So I encourage you to try it sometime!
