Hey there! Did you know that even in your own home, there are lots of cool things to discover? Many common objects have secret purposes that not everyone knows about. Let’s explore some of these hidden secrets together!
Have you ever noticed the blue bristles on your toothbrush? They tell you when it’s time to get a new one. When they fade, it’s time for a change! And those loops on the frame of a shopping cart? They’re perfect for hanging fragile items like eggs and bread so they don’t get squished by other groceries.
Did you know that the tab on a soda can has a hole for a straw? Just twist it around, and you’re good to go! The metal tip of a tape measure has a slit to hook onto nails or screws, and you can even use it to make marks if you don’t have a pencil handy.
If you need to open a glass bottle without a bottle opener, hold it by the neck and press your thumb on the lid. Tap your wrist gently, and the cap will pop off! And if your scissors are dull, cutting fine sandpaper or aluminum foil can sharpen them right up.
Coins have ridges on the edges because, in the past, people would shave off the sides to make new coins. The ridges show the coin is still intact. And that little square piece of fabric that comes with new clothes? It’s for testing if the material fades or stains in the wash.
The side holes in Converse shoes are actually for laces. Loop your shoelaces through them for a better fit. And the blue and red parts of an eraser? The red side erases pencil marks, while the blue side is for tougher paper grades.
Unfold the pleated paper cup you get for condiments, and you’ll have more room for dipping! The same goes for take-out oyster pails, which can unfold into a plate. A utility knife has a removable part to snap off dull blades, revealing a new sharp one.
The hole in a frying pan handle can hold your stirring spoon, and a pasta spoon’s hole measures one serving of spaghetti. You can even change which side your fridge door opens on by moving the plastic caps on the door.
Your car’s headrest can break a window in an emergency, and the small dot on the back of an iPhone is a microphone for noise cancellation. The tiny hole in a lock lets water drain out and is where you add oil if it jams.
Wooden hangers are often made of cedar because it smells nice and repels bugs. The bumps on the F and J keys on a keyboard help you find the home row without looking. And did you know that tapping the “57” on a ketchup bottle helps get the sauce out?
Tri-colored toothpaste is a marketing trick, but solid-colored toothpaste has the same ingredients. You can polish silver with toothpaste or ketchup, and the flaps on juice boxes help you hold them without squeezing out the juice.
So, next time you look around your house, remember these fun facts and see if you can discover even more hidden secrets in everyday objects!
Grab your toothbrush and a shopping cart (or a picture of one) and investigate their hidden features. Observe the blue bristles on your toothbrush and discuss why they fade over time. Then, look at the shopping cart and identify the loops. Think about how these features make life easier and share your thoughts with the class.
Find a soda can and a tape measure at home. Try using the tab on the soda can to hold a straw and test the slit on the tape measure by hooking it onto a nail or screw. Discuss how these small design elements can be helpful in everyday situations.
Bring a pair of dull scissors and some sandpaper or aluminum foil to class. Practice sharpening the scissors by cutting the material. Then, try opening a bottle using the tapping method described in the article. Share your results and any challenges you faced with your classmates.
Examine a coin and a piece of fabric from new clothes. Look closely at the ridges on the coin and discuss their purpose. Use the fabric to test for colorfastness by washing it with soap and water. Share your findings and any surprises you discovered.
Bring a paper cup and a take-out container to class. Practice unfolding the cup and container to see how they expand. Discuss how these simple tricks can make eating and serving food more convenient. Share any other kitchen tips you know with the class.
