Giant jenga, the 6 foot version of the classic tower-building game beloved of student pubs around the country might just be perfect for summer garden parties. The sheer size of the thing adds bucketloads of tension to the game, it really does make a spectacular crash when it falls. Giant Jenga can be purchased at a number of online stores, but it’s pretty easy to make your own if you’re that way inclined, plus you can have custom colours - they’d look pretty cool in day-glow paint!
