A 'human slingshot' made of 100 square feet of spandex is either the best or worst toy you could inflict on your friends this summer.
Essentially a big rubber band, the aim is to propel yourself and three friends in a constant, terrifying dance around the garden.
The key, its makers remind potential purchasers, is to always move right. If you do, you should avoid any catastrophic collisions with your friends.
"To begin, you form a square. One pair then runs toward each other (always passing to the right) until they reach the other side of the square. As they hit the fabric, they rotate their bodies 180 degrees and lean their backs into the fabric wall. Their force slingshots the other team across the square!
Repeat this crisscrossing action until someone decides to "exit" the square."
They also insist that it's not dangerous - well, not unless you decide to make it dangerous:
"Just like a car, it's only dangerous if you hit someone else. And just like driving a car, as long as you stay on your side of the "street" inside The Human Slingshot, you'll be fine!"
Take a look, above.
Classic Super Soaker 50
The original that started it all. The Super Soaker 50 was introduced (believe it or not) all the way back in 1989. It was brought back as special edition 20th anniversary version a few years ago.
Nerf Super Soaker Scatter Blast Water Gun
The modern descendent of the 50, this has the advantage of firing wildly in a number of directions meaning your opponent is in for a close-quarters drenching. <a href="http://www.amazon.co.uk/Nerf-Super-Soaker-Scatter-Blast/dp/B00416LP4E/ref=zg_bs_364278031_29" target="_blank">£25.49</a>
The new kid on the block it the Colossus which with its superb range and accuracy give the Super Soaker brand a run for their money. <a href="http://www.tesco.com/direct/buzz-bee-water-warriors-colossus-water-gun/215-2056.prd" target="_blank">£14.96</a>
AK47 Aqua Fire Water Pistol

Monster Water Cannon
If you simply can't find a gun with a water reservoir big enough then this is for you. This hooks directly to a hose meaning unlimited firepower at a hell of a rate. <a href="http://www.perpetualkid.com/monster-water-cannon.aspx" target="_blank">£26.50</a>
Blurring the lines between water pistols and paintball guns, the Xploderz range fires water pellets meaning higher accuracy and a huge fire rate. <a href="http://www.amazon.co.uk/Xploderz-X-Ranger-Blaster-Gun/dp/B004KKXJG8/ref=pd_sim_k_h_b_cs_3" target="_blank">£17.17</a>
Sometimes water fights has a more serious edge. Like when you're fighting squirrels. And what do you need? A fully computerised automatic "garden militarisation".
It doesn't get much higher pressured than this. Enough power to strip paint means it's probably no the best idea to aim it at someone's face... £91.99
Ok, so it's technically not a gun but this just shows what is capable using high pressure jets of water... at a cost. From £45,000
