We got to play with Gilbert chemistry sets too. If we had possession of some of those chemicals today, we'd probably be on the terrorist watch list.

There could be a good Burma Shave rhyme here.
The first time I went to the dentist he took a penny, cleaned it with his machinery, coated it with mercury and handed it to me.
All nice and shiny. I put it in my pocket, carried it around all day.
The next day my leg was swollen and red where that pocket touched.
Had to go to the doctor and get a salve to put on the area.
Am I mercury poisoned? must be, here I am. :^)

Tin whiskers are NOT unusual, and have been a problem even where no solder is involved.

Assertions that NASA determined that there was no electronic cause for the problem were from a preliminary report (Feb. 2011), a later report (Sept. 2011) changes all that:

As I have been saying all along, regardless of what caused of the “unintended acceleration”, the underlying problem with Toyotas was the fact that there was no brake override of the throttle, a problem that was quietly fixed during the course of the recalls.
This problem (and the solution) was demonstrated in this video:

All this stuff about the government “going after” Toyota is just hot air.
Toyota DID have a problem, and now they have fixed it.
CAUSES TROUBLE.

Interesting. I didn’t know you could lose your power assist if you let your foot off the brake in a situation like that.
BINGO... the communists and their unintended consequences strike again.

I had paper routes in DC as a kid in the 50’s. After I finished collecting for the week, I’d get on the bus and go to the Smithsonian, or sometimes take the trolley to Glen Echo.
11 or 12 years old at the time.
One Sunday morning the paper (Washington Post) weighed 4 & 1/2 pounds. My 10 y.o. sister helped me deliver that morning. Times sure have changed.
To Washington:

Yes, for a power assist that is run from engine vacuum (very common), this can happen. You don’t actually lose braking, it just becomes much harder to get it, to the point that the weak or elderly can’t manage it. Pumping the brakes, as opposed to simply standing on the pedal, is the issue here.
Park your car and shut off the engine. Step on the brake a few times and note the pressure it takes. After a few pushes, the pedal gets “harder”, that is, it takes more pressure to operate it as the vacuum in the accumulator is bled off.
At full throttle, engine vacuum drops down to almost nothing. I remember my Dad’s ‘49 Plymouth with vacuum operated wipers, which slowed to a crawl under acceleration, but operated at full speed at idle or cruising.
At full throttle, there is little chance for the vacuum in the accumulator to build up so that the power brakes function normally.
RoHS!!!!! Yet another unintended consequence from the glorious European Union.
The Senate needs to require Grassley to get an examination to see how many “tin whiskers” are growing out of his head.
Do a web search on ‘rohs’ and ‘whiskers’ and you can read a lot on this subject. Not surprised.

>> a NASA report found evidence of the whiskers in one Toyota pedal assembly,
Remind me why NASA was/is having financial problems.
We were definitely mini-terrorists back then. Dad worked for Allied Chemical, so he was always refilling my supplies and bringing home new ones for me to try (with strict supervision). Amazing that we didn't blow-up the entire house. Heh.
I never had a chem set. No way, no how my parents would’ve ever trusted me with one!!!
For sure. I remember when I was 13 my Mom had to go to the drugstore with me to sign for my supply of hydrochloric and sulfuric acid. But the guys at the hardware store thought nothing of selling us chunks of carbide for our carbide cannons.
Those were the days when people could still buy dynamite, caps and fuse at the hardware store. I don't recall a single terrorist among them. The explosives were used for removing tree stumps, breaking up ice jams in canals, splitting boulders for removal, etc. Now and then some damn fool would injure or kill himself playing with dynamite caps but that's Natural Selection at work.
