Not all projects have to be serious right? Took a little bit of time to build this, but was a fun little project and will make great gifts for nieces and nephews. I started out with some walnut I milled last winter and enjoyed taking it from log to finished project. Sometimes you have to shake the jar for a gum ball to drop, but otherwise it works great. Most challenging part was not eating all the gum balls trying to get the slide perfected!
