Bubble football (also commonly cold zorb football) is a great stag activity and is a fun option for your stag weekend in Cologne. Enjoy 2-hour rental of an indoor football field (with the setup and preparations over 1.5 hours of actual playtime) and 8 inflatable bubbles. If your group is larger than 8, you can easily plan with substitutes - 90 minutes of running is a lot of time, so it will be great to take some rest here and there.
Bubble football is an amazing stag party activity - it is a lot of fun for any group size. Football is a great game, but playing it in large bubbles is even more fun. You can bump into your opponents as you wish...being in the bubbles allows you to run into other players as hard as you want. After the game, each player gets one beer - just a little reward for an epic football battle.
