Show a yellow silk, push it into your closed fist and reveal it has changed to an egg. Crack the egg open and pour out the contents. 

Yes, it's one of those supposedly "overdone" effects, but in the right hands, it is still a pretty amazing one full of laughs and surprises. I've performed this, what looks like a 30 second effect, hundreds of times in my career, adding some humor turning it into a ten-minute routine. I'm not going to embarrass this magician by revealing his screen name, but this is the feedback I was left for a Tenyo T 68 Silk To Egg Magic Trick: This is a toy. Not for the serious magician. I had to educate this "serious" magician on the value of collectible Tenyo tricks just because of the name. The real point of this is that MANY tricks you buy are simple and unfortunately many aren't of great quality; you are paying for the secret, like sponge balls for instance. 4 inexpensive pieces of sponge that I've seen some true masters of manipulation turn into incredible 20-minute routines. 

I've often heard young magicians stating old school magic is just that, old school. Seems today if it doesn't take batteries and have a remote-control device, they don't want to do something that requires a little thinking, patter or skill. Although this doesn't require a lot of skill other than being an actual performer handling something other than a remote, which you can teach any five-year-old how to do, it does require some, I'll say it again, old school performing skill. As the great Houdini quoted: The secret of showmanship consists of not what you really do, but what the mystery loving public thinks you do. 

I sell new & used magic in the condition I receive them. I do not sell badly damaged items. I do not repair small defects or clean vintage items due to being reprimanded by collectors because it, "Takes away from the value."
