Over on BoingBoing Maggie Koerth-Baker interviews Jordan Needham about the underwater fort he and his family built at the bottom of a lake.
The dome is vinyl from the local fabric store. We switched from plastic because the plastic was kind of “cloudy” and the vinyl is optically clear. When The Bubble Room is not in use we take the net and vinyl with us and it is just a metal ring sitting on the lake bed. It takes one person about 15 minutes to attach the net and vinyl and fill it with air.
All the materials except for the vinyl where free!
