34 Amazing Facts About Boring Objects in Your Home

The Color of the Tag on your Store-Bought Bread …
… tells grocers what day of the week the bread was shipped. Bread is usually delivered fresh to stores five days a week—Monday, Tuesday, Thursday, Friday, and Saturday—and each day has its own colored tag or twist tie.

That Tiny Pocket on your Blue Jeans …
… is for your pocket watch. Well, maybe not yours, but the cowboys who made blue jeans famous in the 1800s were plumb grateful for it. Typically, watches were carried on chains and worn in waistcoats, but hard field labor made that a lot less practical. Outdoors, the “watch pocket” on any pair of jeans did just the trick—even after watches moved to the wrist. “This extra pouch has served many functions, evident in its many titles,” the Levi Strauss website reminds us: “frontier pocket, coin pocket, match pocket, and ticket pocket, to name a few.”

The Hole in Your Pen Cap …
… is there to prevent choking. BIC first added the tiny punctures in the top of their pen caps in 1991 both to equalize pressure inside the pen, and to give cap swallowers a last-ditch lifeline; if a cap gets lodged in someone’s throat, they will still be able to breath through the hole. This may sound like an irrational fear, but according to Business Insider, more than 10,000 people have swallowed parts of pens and pencils. Lego mini-figures have holes in their heads for the same reason. Plus: These are the secret hiding places in your home thieves will never suspect.

A Waffle Iron Inspired One of the First Pairs of Nikes
Bill Bowerman was a track and field coach in the 1950s who didn’t like how running shoes were made. He first created the Cortez shoe, but still wanted to make a shoe even lighter that could be worn on various surfaces.

An Avocado Is Not What You Think It Is

Ball on the top of a Stocking Cap

“57” on Heinz Ketchup Bottle
Suppose you thought the 57 on a Heinz ketchup bottle just meant how many previous attempts were made at the formula. Well, it means a couple of things. The Heinz Company used to advertise 57 varieties of pickles it sold but it sold greater than 60 products before adopting the slogan. It seems Henry Heinz picked the numbers 5 and 7 for 57 independently of each other. Heinz said 5 was his lucky number and 7 was his wife’s lucky number. The other secret behind the 57 is that is where the company suggests people tap on a glass bottle of ketchup to make it come out of the bottle.

Secrets of the Tape Measure Hook
Millions of people use tape measures every day, but very few of them are aware of all the different ways that they can be utilized. If you look at a quality tape measure, you’ll see that the hook at the end has a few unique qualities. One is that it should be slightly loose on its rivets. This allows it to slide in or out to allow for accuracy whether taking an inner or outer measure. This also means that the first inch on a tape measure is inaccurate by the amount of that movement (usually 1/16 inch). So if you need to take the measure of a small item, use a section further up the tape.
Another feature is the hole in the tape measure hook. Not all tape measures have this feature, but if yours does, you’ll notice that it’s exactly the right size to latch onto the head of a screw or nail. This allows DIYers to latch onto a fastener head and get on with measuring without worrying about the tape popping free. For more great tape measure tips, check out this video from Family Handyman editor Travis Larson.

Scribing Tool
Let’s return to that amazing hook at the end of your tape measure. Look closely and you’ll notice that the hook is strong metal, and many models have a hook with a serrated edge. This is no accident! It’s an intentional feature, allowing the hook to be used as a scribing tool.
The next time you can’t find your carpenter’s pencil, measure backwards from the edge of your work material. Pull the tape hook taut against its rivets, then push it into the wood or other material. The serrated edge will leave a mark in the wood fibers, allowing you to scribe for the perfect cut. No pencil required!
