It looks fantastic! It's nice that you could work on it with your kids. Icing on the cake that you could make it cheaply, too!
Shadowbat that came out great. Love it lit up in the dark too. Thanks for the video. Very creative and kudos to the kids for the ideas to "tech it out" and they did a nice job putting it together. It really is the Journey as they say! And I bet when they are in their later years they will always remember the alien chamber that you guys built. Can't wait to see your alien room this year. Definitely gave me some ideas for when I do mine.
BTW I've considered a cryo chamber using a sonotube. Using the box with the curved plexiglass really worked. Oh and I wanted to ask what store do you buy your metallic poster board from. Can't say I've seen any out her in my area.
