This is ultimate fun! Anyone who sees a few friends loading up a water balloon launcher tends to run over and want to see how far the water balloon can go! But the title of this water balloon launcher is a little misleading. There is no way we were able to achieve the 500 yards like in the title of this launcher today.
In theory you might be able to get 500 yards if:
1) You have some kind of super balloon that doesn't pop when this amount of force is applied.
2) You mount this to a very stable launching platform
3) You replace the pouch with something that will hold balloons safely and spread the force across the balloon
4) You have nerves of steel (and a wench) to pull it back to the point where it will launch that far
To get the maxium distance during our test today, we had to use balloons filled to about 30% capacity otherwise they just exploded either on the launcher or 2 inches away from it. But during our best launch was about 300 feet which is quite impressive, and crowd pleasing, but nothing near 500 yards. Bottom-line is this is a very fun toy. We loved launching the water balloons!
