After a storm, when the power is restored, check the cup. If the quarter is unmoved, the freezer is safe. If it\u2019s partially submerged, you had some thawing, but the freezer contents are likely still safe. If the quarter is at the bot- tom, you had a significant failure and the freezer\u2019s contents are likely spoiled. By the way, if you do end up with a fridge or freezer full of spoiled food, check your homeowner\u2019s insurance policy. Spoiled food is usually covered (if not the result of flooding).<\/p>\n<p><strong>Writing the Combination Directly onto a Lock?<\/strong><\/p>\n<div id=\"attachment_36899\" style=\"width: 610px\" class=\"wp-caption alignnone\"><img aria-describedby=\"caption-attachment-36899\" decoding=\"async\" loading=\"lazy\" class=\"size-full wp-image-36899\" src=\"https:\/\/tkdev.kk.org\/cooltools\/files\/2020\/08\/masterlock.jpeg\" alt=\"&quot;Hey look, this numbskull wrote the combo right on the lock!&quot;\" width=\"600\" height=\"600\" srcset=\"https:\/\/tkdev.kk.org\/cooltools\/files\/2020\/08\/masterlock.jpeg 600w, https:\/\/tkdev.kk.org\/cooltools\/files\/2020\/08\/masterlock-150x150.jpeg 150w, https:\/\/tkdev.kk.org\/cooltools\/files\/2020\/08\/masterlock-300x300.jpeg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><p id=\"caption-attachment-36899\" class=\"wp-caption-text\">&#8220;Hey look, this numbskull wrote the combo right on the lock!&#8221;<\/p><\/div>\n<p>Here\u2019s a great little trick for remembering a\u00a0<a href=\"https:\/\/geni.us\/NEJxG?utm_campaign=Gareth%27s%20Tips%2C%20Tools%2C%20and%20Shop%20Tales&amp;utm_medium=email&amp;utm_source=Revue%20newsletter\" target=\"_blank\">combo lock<\/a>.
