Okay troops ...... IQ test here.

Place one each in the below posted picture down in front your kids, and see if they can figure out the relationship between the two. :D

Want the tape tighter? Use the eraser end.
Tired of the tape or problems with the tape? Use the pointie end. Slip it under the tape; hang on to the pencil. Drop the cassette out the window at about 70 mph.

LMAO. yeah.... :D

Not only gives the correct answer, he throws in the bonus answer too - Good job!

That reminds me of these two gems...which were quite the rage about 30 years ago.

Age Test -- or, Research Speed ??
 

Very new here, thus correct me if required.

The Etch-A-Sketch and the Spirograph -- were WONDERFUL !!
And yes, I remember S&H Green Stamps.

To the man who says he is getting old -- it's better than the alternative .
(In case you haven't heard that one, before)

Ahhh! A laser disc and a laser disc player! For my money, it provided the most outstanding picture yet, and the best was made by Pioneer. Got mine in ealry '83 in Dallas. You had to turn the disc over by hand halfway through - great for bathroom breaks.

Mine still works and resides with my younger daughter in the LA area, along with the discs she wanted. I pared down my possesions, but I visit it often.:D

12AT7 amplifier tube
 

The 12AT7 was a common amplifier tube, as I recall .

Yes, the X-RAY machine for feet, in a large wood box, with shielded face ports -- mid Nineteen Fifties . [Edited Addition:] There it is (photo) on Comment No. 40 .

Absolutely yes !!
(the general all-purpose circular slide rule --
works even for NON-Atomic calculations)

I have it still .

30 years ago? We had those on our E model Commando Solos until we switched to the J model. That was about 10 years ago.

Not that they worked. They were mounted at an angle overhead, totally against what the instructions said (mount on a level surface).

The first time I saw one in use was in 1983. Watched Apocolypse Now at a friends house. His dad had the thing wired through his stereo. The scene where the helos are inbound and Flight of the Valkryies is playing...made the chandelier shake in another room. Coolest thing I ever seen (at that time) and made me wonder how someone could have a movie theater in their house.

Good catch. Still in circulation big time, most commonly-used audio pre-amp tube around usually in a circuit with a 12AX7 or two. Quality ones are still appreciated in both mixing boards and tube-based transceivers, and any guitar player worth their mettle.

TV I grew up with was a Hoffman b&w with ~12" picture tube, tucked into a f'n 250-lb piece of cabinetry, and 2 big tube trays accessible from the back. Dad never did manage to spark himself; after static issues in early B-29's he was always careful about making sure that he wasn't the ground.

Then someone in the neighborhood got a color TV and the suburban arms race was on...

There's an app for that. :p

I took the aluminum foil a step farther as well. Okay two steps. The first was I would also tape a couple of large sheets (3-4) feet on the wall behind the t.v., in addition to the wrapping the antenna/s.

I was vested in the power of aluminum foil, and as a kid (12-13), I grabbed the aluminum foil from the kitchen, went in the back yard and stretched out about thirty or fourty feet in all kinds of directions, taped to the fence, awning, walls, etc. And the different ends of sheets I wrapped around standard electric wire (another 30 feet of wire), which I had stripped, and spliced this into the speaker wires in my "boom box," to which I then hit the record button, and stayed up all night outside, flipping the cassette, and waiting for the inevitable contact with E.T.s, which never came.:(
