When I first saw these bubble soccer balls for sale I thought of the Human Slingshot. Of accidents waiting to happen. Of Darwin Awards. But apparently this is a sport that has been around Europe for a while, and is beginning its rise in popularity elsewhere in the world. According to Battle Balls, maker of these inflatable bubbles o' body bashing, the Germans call it Loopyball, and other European countries call it bubble football, and it all started as a joke acted out by 2 dudes on a Norwegian comedy sports show. Thanks to YouTube their skit then "spread across Europe like warm Nutella."
Now both individuals looking to pass Saturday afternoons rolling, flipping, and ramming one another in the yard, or teams interested in starting a bubble soccer league, can cough up wads of cash--big wads, these aren't cheap--for their own Battle Balls.
The equipment itself is made of 0.8mm thick PVC plastic, inflatable into spheres with inner handles and adjustable shoulder straps for leverage and so that balls won't go flying upon impact. The listing here shows Battle Balls' 1.5 diameter size, though the company does sell smaller versions for shorter users. Fill time ranges from 2-1/2 to 4 minutes and can be done using pretty much any inflation pump with a 2.8 psi fill capacity, or even a shop vac.
Battle Ball use and bubble soccer endeavors are not recommended for anyone under the age of 18. Check out the video to find out why.
