If you're looking for a serious water blaster this if the deal for you! The Entertainer have this Storm Blasters Hurricane Warrior Water Blaster at half price, down from £20 to just £10.
This is a really massive water pistol, and it works by letting loose a jet of water with it's pump action. It can fire up to 10 metres and holds a whopping 2000ml of water so that battles can keep going for ages!
It's recommended for older children aged six and over, and reviews do suggest that younger ones will struggle with it, especially when it's full with water - but it sounds like great fun for bigger kids!
