Ghost message egg by loup226

This may look like a regular, innocent Hard-cook egg¦ but what you cannot see is egg-actly what makes this egg so special! Pass a secret message to your friend using this trick. On the outside, the egg looks like any other egg. When the egg is peeled however, a message is remarkably written on the egg inside.

Step 1: What you need:

Fine-tipped paintbrush, toothpick or Q-tip

lemon juice works quite well

This is cool but is it o.k. to eat the egg? I would hate to waste a perfectly good egg.
bettbee says: Feb 28, 2009. 5:12 PM
Yes. Alum is used in cooking. For example to make pickles crispy and in baking powder.

would pickle juice work instead of alum?
schorhr says: Dec 29, 2007. 3:24 PM
I guess other coloring stuff might work? Anyway, about eating it: Alum is used in blood stopping sticks, nontoxic clay, deodorant crystals and in chineese fried Youtiao so my guess would be its eatable?

One wonders if it would be possible to dye the eggs afterward so one could have secret message easter eggs.

sweet... im gonna try this but im too lazy to buy alum... will any other spices work?
bettbee says: Feb 28, 2009. 5:17 PM
You can try baking powder if it contains alum, just be aware there may be a bit of a reaction when you add it to vinegar. I'm sure nothing violent, but use a large bowl with a wide opening to mix them in, in case of foaming.

all hail the egg*bends down in prayer* *chants* thank the hen and the cock for this natural marvel, thank you swine for offering your meat in our quest for breakfast salvation, thank you bread for making sandwiches from the marriage of the two sacred aliments*chanting ends*
Aburame Shino says: Feb 11, 2008. 6:06 PM
*childish giggle* He said cock.
Tobita says: Feb 11, 2008. 7:06 PM
cock is how you say the male chicken in english right? my maternal language is french:~/
Aburame Shino says: Feb 13, 2008. 6:47 PM
Actually, Cock is just one way to say it. There is also Rooster. But Cock in english is one of the many slang terms for *ehem* penis. So I laughed.

Kelso's girl-Could you show me the test?

santy22 says: Oct 4, 2008. 3:16 PM
OMG Vagina is not funney, but whan a teacher remarks the word like mine, it gets hilarious and then, this little pieces of skin over THE VAGINA are .....[...] Then, the PENIS gets into the VAGINA.....
Tobita says: Oct 4, 2008. 7:42 PM
HAHAHAHAHAAHAHA, i fell of my bed reading that xD
Aburame Shino says: Sep 18, 2008. 5:39 PM

blue72 says: Jun 17, 2008. 6:03 AM

balisticjoe says: Jun 28, 2008. 11:02 AM
I watch you. And thats also what it says on the egg
swissmis76 says: Jun 4, 2008. 8:09 PM
I Love It!!! This will be great, I can secretly freak out my relatives next easter!
chigozie says: Feb 3, 2008. 11:59 AM
You boil the egg after doing this, not before? I would have thought that the liquid-ish (and I'm meant to be doing a chemistry A-level. Hehe.) state of unboiled egg whites would prevent this. I suppose... it's quite viscous, so maybe it stays in place. Interesting though... I'll definitely try it.
Awesome Possum says: May 2, 2008. 5:06 PM
No, you have to hard boil the egg first.
chigozie says: May 3, 2008. 9:14 AM
OK. That's what I thought. To me, the video implied that you had to paint the message, then put the light on to it, then boil it. It makes more sense if you have to boil it first.
Awesome Possum says: May 9, 2008. 11:19 PM
Yeah, what the vid shows is the victim boiling the trick egg, thinking it's a regular egg.
w00ty32 says: Mar 25, 2008. 10:38 PM
paint a cross on your very christian roommate, who also loves hardboiled eggs. hilarity shall ensue. +1 though
Raggedyandy says: Jan 15, 2008. 12:34 PM
This is Awesome, Thank you for sharing this, I am diffenently going to put this in my "TO DO" box for something fun to do with my nephews, We like to do things like this but I also like to try to teach them something at the same time much like my Uncle did with me ;) And to the other poster who asked about other spices, though I did not write the original Post nor and I a chemist I don't think anything else would work The Alum and vinegar work together and form a chemical reaction of some sort and thats how it works much like the Vineger and baking soda trick, Flour just wont do Peace & Light Andy
wesie42 says: Jan 2, 2008. 3:02 PM
does balsamic vinegar work?
Shifrin says: Jan 2, 2008. 2:26 PM
HAHA, this is great! you should use this for a card magic trick or sumtin also
KNOTTYMAN says: Dec 30, 2007. 10:39 AM
This would be a great way to do a card card/message reveal in a magic trick.
