FLOAT! Thinktank 21 is an amazing tank that lets users experience complete weightlessness and the effects of zero gravity by submerging them into the tank, which is filled with saltwater.
The atmosphere is also soothing due to an audio piece by Thom Kubli that is played inside. After the music has played through once, the FLOAT! Thinktank 21 is completely silent so users can get in touch with themselves. The design was created by Kubli for an Art & Zero Gravity exhibition in Germany. Sounds pretty amazing to me!
