Cards vs Gravity Pro by Steve Howe in Bloomington, MN

A card-balancing, gravity-defying game that is more dramatic than Jenga, and more portable. Simply attach the magnetic platform to any bottle, then take turns balancing your cards. Get rid of all your cards and you’re safe… for now. But eventually gravity will get ya! One player will ultimately knock over all the cards. Make sure it’s not you.
Put on a show. Whether you’re playing this game on holiday, at college or down the pub, you’ll draw a crowd. It’s one of those games, like Jenga, that makes people gather around and want to watch the drama unfold.
A take-it-anywhere game. Slip this game in your pocket and play it anywhere. All you need is an empty glass bottle and you’re in business.
Virtually indestructible. This game is perfect for all ages and venues. The cards are made from plastic, so you don’t have to worry about them getting wet, and the platform is made from metal. It’s totally pub and party proof!
