This morning at 7:00 am, the 4th grade Secret of the Fortune Wookiee book club played a Kahoot review game, solved a Murky crossword puzzle, and created light saber cards! The materials you need are: template for card (below on the Left Brain Craft Brain site), 5 mm LED 2 prong mini lights, coin cell batteries , red straws (Wal-Mart), scissors, and tape. I already had the lights from this kit I purchased a while back. For the circuit cards, I prefer the Chibitronics LED sticker paper circuit kits. First, fold the cardstock and poke the prongs of the LED light through right at the top of the light saber hilt. Then cut a piece of straw (start out longer) and slide the straw on top of the LED light. Then tape the coin cell battery to the back, making sure there is a prong per side. This part took some fiddling to get right. Then cut the straw as needed. We found a longer straw made the light look more light-saber-ish.
