Unless you have fingernail polish to remove, anyway. Brands that do, list it prominently on the label.

I’ve only CA glued myself once, and that was to the container the CA came in.

CA is one of the many substances that was invented for one purpose, and ended being used for another. Originally meant as a mean to etch bomb cross hairs into bomb sights during WWII, it was quickly realized that it was actually an adhesive with amazing pull strength (but little shear strength), and almost immediate cure time. Subsequent development during the Vietnam War discovered that if you could close most wounds until a doctor could tend to them, the patient’s survival rate shot upwards. CA was used as a field applied suture, with great success. In fact, subsequent research has shown that using CA as a suture is safer than traditional methods. I’ve used it myself on cuts to the thumb, and can attest to the exothermic qualities of non-medical CA. Best to buy Dermabond or one of the other medical versions.

Did you know that breathing softly (like you do when cleaning sunglasses) on CA glue causes it to bond faster? Water acts as a catalyst, so if you want to hasten the gluing time, a bit of hot breath works great!

Speaking of exothermic, apply enough CA to a cotton ball and the chemical reaction of the CA can cause enough heat that the ball could catch fire. Kids, you can try this at home, but for goodness sakes do so with an adult around. I find the kitchen sink is a good place to do it.

It’s one of those situations where you’re not sure whether to help or to run get a camera.

Very true, and something I should have mentioned. I can’t remember what it was I glued myself to that I asked my wife for her nail polish remover. She can’t either. I thought it might have been the ceiling fan in the kitchen, but I’m pretty sure if it was that, we’d both remember it pretty vividly.
