Has anyone ever launched something from these…just to see how far it would go? One went off right next to me on yesterday’s ride and it was pretty impressive. I reckon the farmer had modified it in some way to be more mortar like than normal. They bring you out of cycling (well, South Downs bimbling) induced calm fairly abruptly when unannounced!

It won’t work tried it (at work) a few times, the gas is released but fails to ignite so no projectiles. The ones we have are adjustable and will release gas into the chamber from 1 to 7 seconds the latter is very loud
