Tip-top
As a kid a rather delightful trick was to i)fill a thin, plastic tip-top drinks carton with fresh dog shit ii)stick a banger in the top iii) light banger iv) throw sufficiently far, preferably over the heads of mate or group of mates v) roll around laughing as shit spattered mates look daggers at you.
It happened to me once but you gotta be able to take shit as well as deal shit :) (it gets fuckin' everywhere hee hee hee)
My other favourite was when I worked in a bottling plant. Some of the drinks bottles had the silver or gold wrappings around their neck. The foil comes from a nice smooth roll and its colours are a spit for gold and silver coins. Sometimes, on nightshift, a mate of mine use to take a piece of foil and make a perfect replica of coins, with great care and patience, wrapping the coin in the foil making imprints of one face and the sides of the coin and then , without creating any creases, tuck the remnants of foil underneath. It was quite an art. Then they would be placed strategically on the floor, catching the light and you'd wait for the unsuspecting victim to come walking past. They would be walking in factory automaton mode when they would spy some dropped change in a couple of pound coins, a fifty and a couple of twenties and their automaton face would register human emotion as their eyes lit up, burning off their glaze, sometimes with a quick look around, then they would stoop to pick the money up, only to have it fold and crumple under their touch which was, by now, reflected in their eyes as their face fell.

It was beautiful.

They would swear and curse, with liberal dashes of colour, at me and my mates sniggering but they couldn't help but admire the effort and genius of the prank.

Mmmm..... I don't feel complete, all to polite..... fuck, fuck, fuckety fuck.

my great grandad
used to do something similar when he was a kid, wrapping the silver foil around a penny and rubbing until the imprint made it look like a silver coin.

one day he tried to spend the "silver" coins. to his glee, the guy in the sweetshop was near sighted and took them. he got tonnes of sweets and was a king for a day at school.

two days later he got hauled up in front of the school assembly and royally caned for it. then he got home and his dad caned him again...

With the aid of a microbalance
and a power drill and a bit of maths, we used to make 'pound' coins by supergluing two old 5p pieces (I think) together and drilling out the correct size of hole to make them the right weight. They would then be put into sweet vending machines in our halls of residence.

Sometimes they even worked. Actually, given the success/failure ratio, we probably broke even at best.

Someone at our school did the shite + banger trick once
only the once mind, as they got kicked in shortly afterwards.
