Water Cannon This has to be the daddy of all water guns. If 'Wet n Wild Rambo' ever gets released (script has been completed in Post-It notes on my desk), this will be his weapon of choice. Our Water Cannon hooks up to your garden hose pipe, giving you an endless supply of ammo. Complete with a tripod, I can almost see the water pistols crying and sweating from here... The Water Cannon is an ideal gift for boys, but can be enjoyed by the whole family! Whether you are looking for a Birthday gift or Christmas gift, you can imagine the amount of fun you can have in the garden with this!
