mmm, I dunno what it is but, ... there is something wonderfully yucky about having a large cold raw egg or two or three placed right on the bulge, and then scrunched !
Then be made to ware it about the place, maybe shopping, club or work!

Does anyone else 'get this', and perhaps could we create a group just for 'eggs smashed in the pants and / or panties. Your thoughts ? ...maybe even as a 'fun' party punishment.

While raw eggs placed inside pockets and then cracked is a cool way to gunge an outfit from within, I'd be a bit wary about having anything as sharp as broken eggshell inside underwear - wouldn't there be a risk of painful jabbing in sensitive areas?

But other than that yes, the idea of something you can drop into your clothes that is clean and dry at first but then erupts in a tide of liquid is an appealing one. i wonder if it would be possible to make some kind of paper pouch full of gunge that will stay dry for a short while but is easily burst open to unleash the flood?

I can attest to the broken egg shells stabbing and/or cutting sensitive areas. It's one reason why my wife and I hate eggs as wam. On your question about gunge or other wam ideas in a paper pouch, yes, it's possible. Use "Tyvex" envelopes. They are those "rip proof" envelopes often used for mailing sensitive documents. They won't rupture as easily, but they do start to leak after a while of moisture from the wam item.

There is a way around this that nobody ever mentions. We wanted to be able to throw and smash eggs on the model and came up with this:

If you soak the eggs in malt vinegar for at least 12 hours the calcium is dissolved and the eggs remain inside a soft, white membrane.

Now that's brilliant, thank you. How fragile are the membraned eggs, will they stay unburst if carefully picked up or gently dropped into clothes? I'm imagining someone in a nice trouser business suit over nice high waist bikini bottoms - which are then well filled with these, along with normal eggs in all her trouser and jacket pockets. And then we set about bursting them.

The best way to do this is to get a funnel and put gunge powder into an empty water balloon, then fill it and shake it well. The balloon can be placed inside of clothing, so long as it isn't too full. Then, when the time is right, the balloon may be ripped open.

This leads to the idea of pranks too. An innocent water-balloon fight can become wild if the balloons contain slime. I recommend clear slime so as not to stain anything.

Another nasty but fun prank is to soak summer clothing in clear slime, then wring it out and let it air dry. Once dry, squeeze the fabric to get the 'crunchiness' out, then fold as you normally would. The clothing items could be a bikini and/or a t-shirt normally worn on top. The victim will go in the water and suddenly find her bikini all slimy and practically slipping off. She'll probably run to shore and put her T-shirt on, but that too will suddenly get all slimy if she was wet from swimming. She may even go back in the water to rinse the t-shirt, but with most slime formulas, it will take time to rinse out of the fabric, leaving the poor victim all slippery and slimy. I've never actually tried this, but I have found it next to impossible to rinse slime out of clothing, and clothing that dried with slime in it instantly returned to a slimy state once wet. Of course, it does rinse out eventually.

A sharp fragment of eggshell can cut like a razorblade.

Optimum. They're tough enough to pile into a bowl without breaking but weak enough to burst on impact if thrown or splatted. The great thing about them is that they don't look all that different from a hard shell egg when they break. I put out trailers with eggs being smashed hard over heads and nobody made any comment about them, presuming they were shells. I'd never throw an unbroken egg at someone's head in a million years.

I'm really surprised nobody has used this trick before.

Awesome, thanks for sharing the info. We will definitely be using this in future scenes, next time we use egg. Thanks again!
