I think you would find very few people to disagree.OMG, you blew up an Apache hood? For my money, the classiest pickup ever designed.
They were great fun. You could make interesting tings like rocket fuel. My oldest sister worked at a lab for a professor who taught both of my parents. He would let her bring home glass ware for the me and the younger brother. And, bottles of chemicals which were aging out, and not usefull in the lab any longer.In hindsight, I can't believe what came in my chemistry set, (strong acids) and what additional chemicals I could easily buy at the local hobby shop (ingredients that could have made explosives), and glassware for moderately large distillations (mostly used for flavorings and floral distillation). I looked at a set ten years ago and the range of chemistry was pretty anemic, and not very colorful, making it easy to pass up as a gift for kids.
All the best,

The only time I did acid was when some jerk cubed me. I did not enjoy either experience. First one I tried to hide in the local theater, which the last time I walked by had been showing a spaghetti western.Sometimes we would make chili or spaghetti and not tell anyone...!
It seems to me that many young people in the 60s and 70s did a little experimenting at that time and denied it through the 80s, 90, and 00s because the climate was not right, but now in the 20s, find the climate change is enough for them to admit what they have been hiding all these years. Even right wing, conservative people were young at one time.
Maybe not always. I saw him in concert in 1959, with Johnny Cash. He didn't wear them then, and when he got on stage, they couldn't find his guitar, so he borrowed one from the band.Roy Orbison always wore sunglasses.![]()
True!Don't know if you can buy them today, but the nets to Coleman gas lamps were radioactive. That's how they could get so much light out of them.
Had a very strange conversation with a passenger on a cross country flight back in the late 70's to a DC area airport. He had a brief case, full of stuff, I'm guessing it was lead lined, and a Geiger counter and wanted to share, or at least tell me something. Said he had something he was invited to present to Congress.
Sometimes we sit next to very strange people on plane flights.
First, at when we got to 30K altitude, he started up the counter and it was near off the scale. He said this was cosmic rays hitting the metal frame of the plane, and sending off radiation. I thought this to be a joke, till I looked it up much later and found some of it to be true. You are being irradiated when you fly at 30K feet or so. Its like having 6 chest x-rays on a long flight But he had another thing he wanted to show me, which was a coleman lamp net. He took one out of the case and the Geiger counter was pegged. This not an Urban Legend . Cause, I experienced this first hand. If he was playing a joke on me, that's Okay. But was it a joke or real? I do not know. I did later test the Coleman lamp nets, and found that they are indeed radioactive.
Never realized Tig tips are radio active...True!
The mantles (nets) contain silk/cotton/nylon impregnated thorium. As a high temperature oxide, thorium oxide is important for the stability and function of the mantles. As thorium is present as an isotope (232Th) that is an alpha particle emitter, be very careful around the dust from a broken mantle! Don't take a deep breath to blow away the ash; it is a great way to suck radioactive particles into your lungs.
Needless to say, the exhaust from a gas mantle contains a few thorium particles, and is therefore radioactive, so using one in an enclosed space isn't ideal, and as the lanterns are also sources of carbon monoxide, there is another reason not to use a gas lantern in an enclosed space.
IIRC: Aladdin made a version based on a kerosene wick lamp that was stunningly brighter than a normal kerosene lamp, and required a rather tall glass chimney to get enough draft.
Gypsum, e.g. drywall, is radioactive for the same reason and a major source of radon in tightly sealed homes. Gypsum contains uranium as well as thorium, and both decay to radium, which decays to radon.

Phosphate rock contains the mineral phosphorus, an ingredient used in some fertilizers to help plants grow strong roots. Phosphate rock contains small amounts of naturally-occurring radionuclides, mostly uranium and radium.www.epa.gov
Don't forget "blue" tungsten TIG tips, some of which contain a fair amount of thorium (2%), which you want to be very careful not to breath the dust, and contain any dust from sharpening. I never understood why some welders thought it was safe/smart to use a powered grinder to sharpen blue tungsten as it sends thorium everywhere.
The health risk with thorium dust in your lungs is that is an alpha emitter. The particles don't go far, but the alpha radiation is enormously damaging to cells in general, and the delicate tissue of lungs in particular.
All the best,
