they look like huge white bullets
They are. The artist visited Verdun and collected bits of shrapnel. He melted it all down and cast it back into bullet form. And then from that he created 91 of these overblown bullets.
He intends to destroy them all. The monitor showed the bullets being dropped and shattered.

Yes, bullets. Giant bullets.
Excellent stuff. I shall have to get a similar shot tomorrow. Assuming I'm, yanno, actually booked on the walk.
Good luck. Our guide never turned up! We had to make up our own walk.
