thats pretty cool. How much powder and cremora is in the big one?

Don't remember. All 7 were in 5-gallon buckets though, and we had pretty much cleared out the local Sam's Club of all the cremora they had in stock. The powder was in a dog dish at the bottom of the bucket to get the blast to shape upwards and not out.

Those are the biggest mushrooms ive ever seen from a 5 gallon bucket. The dog dish must really help. Thanks for the info!

Yeah, you've got to use slow-burn powder too, otherwise you'll blast the cremora to the point where it isn't at a high enough concentration to ignite. Plus, the second and last shots are actually 2 separate buckets that were fired about 0.1-0.2 secs apart from each other, which helped the second build on the first.

Atlanta olympic theme was always the best :)

Good choice.
