Gilbert cloud chamber, assembled An alternative view of kit contents. The lab contained a cloud chamber allowing the viewer to watch alpha particles traveling at 12,000 miles per second (19,000,000 m/s), a spinthariscope showing the results of radioactive disintegration on a fluorescent screen, and an electroscope measuring the radioactivity of different substances in the set.
For the metal foil, they tested a variety of metals, but favoured gold because they could make the foil very thin, as gold is the most malleable metal. [15]: 127 As a source of alpha particles, Rutherford's substance of choice was radium, which is thousands of times more radioactive than uranium. [16]
STEM learning might sound like some kind of fad simply because the acronym is fairly new, but the truth is that kids are hard-wired to find these academic disciplines (science, technology ...
"The 8 Most Wildly Irresponsible Vintage Toys" -- page 1 and page 2 at Cracked.com: Includes humorous discussions of some of A.C. Gilbert's more ill-advised products for pre-teens: A glass blowing kit (#8); a molten lead casting kit (#7); a chemistry set (#3) which included potassium permanganate, ammonium nitrate and instructions on how to ...
His "reactor" was a bored-out block of lead, and he used lithium from $1,000 worth of purchased batteries to purify the thorium ash using a Bunsen burner. [3] [4] Hahn ultimately hoped to create a breeder reactor, using low-level isotopes to transform samples of thorium and uranium into fissile isotopes. [5]
Uranium is notable for the extremely high density of its metallic form: at 19.1 grams per cubic centimetre (0.69 lb/cu in), uranium is 68.4% more dense than lead. Depleted uranium, which has about the same density as natural uranium, is used when this high density is desirable but the higher radioactivity of natural uranium is not.
