Could a vibrator explode?

A vibrator can explode, but it won't be due to moving part, (a vibrator is nothing more that an electric motor with an off-center weight). Battery can explode.

As far as I know, no one died of an exploding vibrator in this past century.

The likelihood of internal mechanical failure leaving enough energy in the eccentric weight to smash the external shell and cause injury should be easily calculable from some of the device's specs and materials, but that's sort of overkill.

If dropping it onto a hard floor doesn't destroy it, the little battery-powered motor inside won't destroy it either.

@dunz, noone here is qualified to answer such ridiculous things. Just because you can post such questions do you really think your going to get a definitive answer here? I have seen post after post of some ridiculous things. This forum is intended to help people who are interested or have questions about prostate and prostate orgasms. We are not here to help with silly stuff like vibrators exploding in your ass nor are we qualified to answer such things. Again I'm not trying to upset you or offend you but can we please keep the topics around here on subject? Perhaps if you are seriously looking for questions to such things you find a forum more suited to the question. In this case a forum suited for sex toys and the potential of them exploding.

If the vibrator is from a surplus army store and has TNT on the side then I would be weary of sticking it in your ass. More so if you smoke.

Perhaps the greater hazard in inexpensive vibes is overheating of inexpensive plastics. Those can 'infuse' toxic chemicals into one's anal canal or rectum. If it doesn't smell good when running, suggest covering it with a condom. (then shop for a replacement)
