Query: Fun for the whole family + excellent upgrade for your spudgun

Not only do all 4 of us college students living here love this stuff (it goes great on pizza, and keeps it piping hot for hours!), our cats have taken a liking to using it as a face-scratcher, and it's done wonders for their coats. Far less dander now, and their glow-in-the-dark tags are even visible during the day!As an added bonus, once you've depleted the entire jar, you can upgrade your spudgun to use depleted uranium rounds! Using high-pressure steel parts instead of PVC is highly recommended if you do this, but the increased range and damage is worth it.
