Calcium carbide, (granulated), 1 pound- Elkem metals

Item has allowed a Carbide Noise Maker Canon to operate at a cheaper price. Thanks. Works well. I am recommending this for all who have these noisemakers.

Although this arrived 4 weeks after date provided, it is amazing for any science pPurposes. I have seen better quality, good deal for price.

I bought this to make soda bottle gas rockets and it works great. It is very small pieces so it dissolved very fast and produces a large amount of acetylene gas. Take caution when wetting this material as it makes an explosive gas.

excellent works great in my old Bang-site cannon I have had for 50 years

Haven't used it yet, but it appears to be a high quality product and for a good price. AAA+++

High quality, powder.

Aaaaaaaaaa
