Two selfmade functional cannons , caliber 40mm.
The concept is to place them directly towards eachother and fire them (speed 200m/s) , so the cannonballs meet eachother in mid-air. For this purpose I casted bronze cannonballs.
I did this on 29/05/2021 in the art gallery Barbé Urbain (Gent- Belgium).
The experiment lasted 0,05 seconds. The balls shatered in countless pieces of shrapnel.
It was the first time in history that somebody tried and achieved this goal.
