My students spent a couple of weeks developing ideas and creating fragile projects and when they were finished I put them in a barrel and set them on fire.
Typing that out helps me see just how odd it may seem to you. It also explains why some students were so nervous about the idea. It's easy to get so caught up in your own little world that you forget just how odd some of your routine experiences may seem to others.
All the projects survived and the results were great.
