Learned how to do that my Freshman year of college.
Luckily, my father hated liver even more than I do, so that particular dish was never a problem. Mom’s 4 Bean salad, OTOH…to this day I cannot and will not eat wax beans or lima beans, and kidney beans only when they appeared in my wife’s chili.
The bits make great confetti. Sometimes other card colors were used, but mostly that manila color. Punch cards are good and stiff and useful for cardboard construction projects. I would crease them lengthwise and use a stapler to build geodesic dome models out of them. I was also an expert in their intended usage, keypunch machines, sorters, duplicators, card readers, punches, and whatever the machine was called to print on the cards (a lot of card punches, the machine a computer uses to punch new card, did not print on the top of the card like keypunch machines did). I could also program the patch board controls for them.
Christmas wreaths made of the aforementioned punch cards. Fold, staple, assemble, spray paint color of your choice. Mine were always gold.
We also made Christmas trees.
Adjusting the antenna to get a clearer picture on the big 3 networks, or on PBS, or on UHF. (It had to be pointing in different directions for each. Dad eventually installed a BIG antenna on the chimney that had a motor that let us rotate it from a box sitting on top of the kitchen TV.)
“It’s Cal Worthington and his dog, Spot!”
I think growing up he had every kind of animal, except a dog.
Although chad confetti looked fantastic thrown out of a high window it was too tiny and would get in the eyes of people in the street below. NYC banned the practice.
Chads from paper tape was much finer than chads from punch cards. I did typesetting with paper tape for many years, and I know from experience what it’s like to have a container of chads dumped on your head.
My mom was going through one of her many artsy-fartsy phases. She set up an assembly line to make punch card wreaths in our basement. My job was to spray paint the cards with canned spray paint. The lack of ventilation in our basement made the job a lot more enjoyable than it should have been.
People still do this. I did this last year after our move. Antennas large and small are big sellers online. Some are of the classic rabbit ears form.
People cut the cable (at least as far as TV service goes) and use an antenna to watch the local stations. Stream for everything else.
Push-out triangular side windows in cars. I still wish they were a thing now!
Leaving your empty milk bottles (with money underneath) either on the front veranda or near the driveway for the milkman to swap for full ones.
Going to the local ‘milk-bar’ with 20c in your hand and coming back with bags-full of lollies (and milk). Milk bars don’t exist here in Aus pretty much any more.
Our dairy provided an insulated metal box for the milkman to leave the milk in on the porch. When payment was due, my patents would put a check in an envelope and put it in the box with the empties for the milkman to collect.
We left cash. If I recall correctly, a pint of milk back then cost 7c, so a 5c + a 2c piece were left as payment.
When I was a little bit older and getting into some mischief with friends, we’d do raids on doorsteps and steal the milk-money from under the bottles. Thank goodness I didn’t continue with such a life of crime.

I used to take my $5 allowance down to the corner store strip mall a mile away (unsupervised on a bike) and spend it on ice cream or the arcade and whatnot. I learned my math skills spending every cent on penny, nickel and dime candy bins. Good times.
Every neighborhood had a corner store. They carried the same items a convenience store carries now but these were usually family owned and operated. Ours had a butcher shop in the back.
Less than two miles from me: three lanes and an ATM on the corner.
I’ve used that ATM because it’s often less busy than the one on the main drag.
Running over the hose at the gas station to make the bell ring. The little cardboard washer in the top from a soda bottle.
Later tossing the pop-top into the can but then worrying that you’ll accidently swallow it and it will slice open your throat and you’ll drown in your own blood. But really you should keep the pop-top and give it to the American Kidney fund to buy dialysis machines.
