Rubik's 4x4x4 Cube: Underwater, goggles, no breathing equipment
11 minute 22 secondsMatt WalterThanks to Gilles van den Peereboom for lending me his competition cube that he would use two days later in the czech open.(after being cleaned and lubed carefully, it is back into speedcubing standards)20060722
22 minutes 2.24 secondsStefan PochmannI got this cube that I don't really like so I intend to solve it underwater. Gotta get faster first, though. This was close to suffocation (just kidding), thanks to both parity errors. Inspection not included and I did breathe during it.20040824
