The Spacebuster is build on the basis of a step van and a big inflatable space coming out of the back of the van fitting up to 80 persons in it. People enter the bubble through the passenger’s door of the van walking through to the back down a ramp right into the inflated space. The bubble is supported by air pressure generated by a fan underneath the ramp. The membrane of the bubble is translucent so people on the inside can see schematically what´s going on outside and vice versa. So the membrane acts as a semi permeable border between the public and the more private.
