If you’ve ever had the pleasure of participating in a water balloon fight, you will concur that the most frustrating part of battle is reloading. You think you’ve got an uninflated balloon securely attached to the end of a garden hose, and then as soon as you turn on the water, *snap*, the balloon comes flying off. Or maybe you don’t even get that far — the balloon breaks as you’re stretching it on. Or you get it all filled up, and then you can’t tie it and it drops and breaks on the ground. Now some ambitious inventor has come up with a solution to all those problems: a device that lets you easily fill up 37 water balloons at once, and 100 in less than a minute.
