We've made the Air Rocket Launcher in this video and if you go to the link, print out the template, and put together the rocket, you can come by the library and use the launcher to test out your rocket. Please contact Mark McKnight to set up a time to launch your rocket.
If you want something more challenging, check out this video on how to create your very own Baby Yoda! There is a link below the video where you can get the template for Baby Yoda completely for free. And if you find that you really enjoy this type of craft this guy has a bunch more free templates on his website including a Mandalorian Helmet!
