Water gun fighting is always fun, no matter if you’re a child or an adult. But water gun fighting at night is even more entertaining! The only problem is, that you can’t see the water so clearly… And that is why our beloved inventors came up with bioluminescent water guns. This blaster styled gun is filled with a special ReLume with natural bioluminescent proteins, which, when mixed with water, create a bright stream that remains (!!!) glowing even after it’s been shot out! Yes – that means that you will clearly see who missed and who aimed successfully at the target. It’s non-toxic, so no worries – go and prank your friends or scare your cat. We don’t care. As long as you have loads of fun with it.
