The CyberSquad has available different-sized air tanks to travel to Crab Kingdom. The higher the capacity of the tank, the slower the bike. They try to estimate which tank size will be enough for the round trip to Crab Kingdom. Matt takes the six-minute tank to check how long it takes to travel to their first destination, which he verifies to be six minutes. While they can take the 18-minute tanks, they estimate high to be safe and decide to take the 24-minute tanks.
