Poppers, poppers, and more poppers. I cut them into a rough size with a razor blade then thread them onto a needle and chuck them into the dremmel tool to turn them round and to a final size. I really like poppers alot and this makes it much cheaper since I got a 10lb bag from a winerey close by for a five spot, and trust me 10lbs is a lot of wine corks.

P.S. they take to paint really well also
