How many things are there not to like about spit balls that glow in the dark, cost under $5, grow to 200 times their starting size when soaked in water...or, you know, spit...and explode upon target impact? Zero. Zero things clocks in as the correct answer, so stocking stuff away, everyone. Each Glow-in-the-Dark Spit Ball package includes over 50 super-absorbant pellets that claim to ooze psychedelic green for hours, and reach full bloating capacity at around 120 minutes of soaking in liquid. Whoa. That's kind of a long time to suck on one. We might need the saliva of Violet Beauregarde to step in and assist.
And if you're going to get the ammo, don't forget the gun. This one's rapid fire, and can hit targets up to 65 feet away.
