Now that I have an alarm clock that sounds extremely similar to a smoke alarm, it’s entirely possible that I’ll just try to smack my alarm clock if the smoke alarm went off and fall back to sleep. However, I would still choose my blaringly loud high pitched smoke alarm over a Wasabi spraying smoke detector. This smoke detector spurts out just enough Wasabi to wake you up but not enough to blind you (which is nice of them). Apparently it only takes 2.5 minutes to wake you according to the creators. If you are a big fan of this method, you can purchase one for $560. Although it will be difficult since it comes from a Japanese company.
