I don’t know what I think of this art installation. Sometimes I see a giant alien playground from the future, other times I think it’s a sticky membrane web from the inside of some sci-fi monster. Whatever it is, every single time I see a lot of freaking fun.

The installation, called On Space Time Foam by artist Tomas Saraceno, lets people just walk inside, outside and all over the clear plastic film and it’s like hiking a plastic mountain with grooves and slides and non stop fun. The floating structure is “composed of three levels of clear film,” which hopefully won’t tear.
