I’ve made a video for my Youtube Channel in case you missed it. Seems like this would be great for science fair projects for young kids. Watch the Video Here.

Each 2-part case was a bit over $3 in “White, Strong and Flexible” material. (They’re small) and shipping for orders over $25 is free. Read the rest of this entry »
