Winter is here, and so is the possibility of power outages due to ice storms in my area. When the power goes off just just an hour or so, you’re pretty sure the stuff in your freezer is still okay, but what if the power is out for most of a day or more? If you’d rather not just routinely chuck out everything in your freezer every time there’s an outage, the Spoiler Alert from The Container Store will tell you if you’re safe to use the food. You simply shake the Spoiler Alert, turn it upside down, then freeze it for 24-48 hours. After that, you turn it right-side-up, and it’s ready to let you know how many days you have to safely consume the food in the freezer. If only the blue section thaws and runs into the bottom compartment, you have 2 weeks to use the food; if the red has melted, you’ve gotta throw it all away. The Spoiler Alert can be used over and over again; simply go through the freezing process to “reset” it. It’s out of stock online, but you can pick it up in your local Container Store for $12.99 (currently on sale for $9.74).
