Pack of 24 Bottles of Magic Disappearing Ink

Excellent purchase and it works just like I remember! I bought this novelty as a toy for the treasure box in my classroom, and it's been a HUGE HIT - for all ages! I teach K-6th grade Math Lab, and just demonstrating this today captured the attention of every class! :) The ink disappears fully - I even used myself as the "test-dummy" today and squirted this all over a nice white, dressy blouse that I wore, and to the amazement of my students every spot of blue faded away before their eyes! My blouse is 100% polyester, and it worked great. I also doused my red/white tie-dye skirt that is a combination of rayon/spandex, and it totally disappeared from that also. I tried it out on several students that were wearing simple, light-colored cotton shirts, and it again worked like a charm. I will definitely purchase this item again and my students are clawing at the chance to snag a bottle. This would also be a neat science experiment/lesson to try! :) The ONLY issue that I had was during shipping, the box must've been jostled around and several bottles had slipped out of the insert that held them in place. The ones that shifted around must've gotten smashed, or damaged in some way, because they leaked out and were either empty bottles, or the fluid was clear (because the "ink" was exposed to too much oxegyn and disappeared). I emailed the seller yesterday but have not received a response yet. I will update my review when/if I hear back from them. Overall, this was still an excellent find, the kids loved it, and I WILL be buying this again - probably very soon!!

All of the bottles arrived still blue. Some people are disappointed with it because they wanted to just watch it. The fun is squirting some on somebody's clothes or something a person would freak out over staining. After all, that's the point of the product, not to just pour it on a napkin and be amazed (although testing it on something first is always a nice idea) I didn't buy it though for pranking, I make soap and wanted to experiment with it since the ingredients are of interest to me. I did put it on a paper towel to bring back childhood memories of watching it disappear. So, overall, it worked like it should. If you squirt it on something with a pH above 9.3, it will not disappear. If you want to reactivate just for fun and make a cool trick out of it you can rub a cotton ball of ammonia over the spot you squirted ( if it's something you don't mind getting ammonia on). I would highly recommend researching the ingredients in disappearing ink so you know what you're getting and if you end up with a clear bottle you can see what you can do to still make it interesting for kids (with adult supervision).

A fun thing. I thought I searched for non-toxic and chose the first option, but when I got it the directions said do not put in mouth! That’s why I got it because I wanted to spit it!There are several bottles of ink that are clear—not blue!!! What’s that?

We got these as party favors for my son's magic themed birthday party. They were hilarious and disappeared so completely that I actually tried it on my new white shirt (just a cheap one, I'm not that reckless) and it left no mark whatsoever.The only disappointment was that 4 or 5 of the box of 24 were clear when we opened it. I read that in other reviews as well so be sure to over-order if you're counting on a certain number of bottles.All in, for the cost, it was fun to try and perfect for our party theme

I used this magic disappearing ink for my kids' summer program and it made a blast among the kids. We used it on white bed sheet and it looked very dramatic when it was poured onto the sheet. Several kids were stunned and shouted why did I do that? Haha! Then when the ink is dried up there is no trace left on the sheet. Very nice. With the box it's a very good deal. I'm planning to use it with other kiddo groups in my community in the future. I have plenty left.

Not sure if I will return because the product was not very expensive. However 8 of the bottles were colorless and had already lost their color. The rest of them were good however.

Bought for prizes. Would be great for goody bags and or party favors. Nice size, work well and the kids live a prank!! No complaints of stains so overall a big success. I would recommend to others.

I had lots of fun playing with invisible ink as a kid.... so I decided to buy this to put in my son's 1 year birthday goodie bags. Lots of parents were not thrilled...but I had a good time playing with it!!! Still scary every time you pour the ink on!!!
