You could place several pies on a long piece of paper and slowly pull the paper off the table so that each pie gets to the edge and falls down onto your waiting face. The pie would need to spin a half turn to land cream side down; or a higher table top would allow a full rotation before landing. Physics really gets involved. But it would be fun to experiment.
I'm not sure the exact terminology but I'd said it's just submission bc the receiver has no way to avoid it...I would love to hear the name of it too so I can make a vid...great question mang! And with the table....take a heavy pillow , couch unit maybe and pull it off and see how it falls then just trial and error with a crust full, mark the landing, wouldn't hurt to do it twice then u can mark the floor so u know how it'll land, it's good to do it with a pie too yo see how the crust reacts, the pillow I'd just for weight, then u have a splat zone! Hope u try n post!
I've loved doing this since I first thought it up many years ago, then I discovered other people were already doing it. A pie friend nicknamed it "the patented pie drop". I found it the best way to keep gunge on a face (mine or someone else's) w/o sliding off.
