“A Superior Bubble Fluid”

Do you need some superior bubbles? If you’re in the time window between 1961 and 1991, Better Bubbles, Inc. of North Hollywood, Calif., has got you covered. Or, if you’re like us, and you happen to have some of this stuff still around.

Better Bubbles went out of business 32 years ago, so once we’re out of this fluid, we’re out. It is, to be honest, quite superior to the usual soap bubble liquid for kids, at least as far as creating durable thin-film interference patterns. We work diligently to minimize any actual bubbles.

Of special note: the directions for use. The label says “Do Not Dilute,” which seems an odd choice as this stuff flows like thickened liquid dish soap on an icy morning. The lid asks not only for dilution, but actual shaking, which can only result in a I Love Lucy-esque eruption of unending soap bubbles. A hand-written note – clearly the tested and preferred method, and the one still in use – calls for approximately 1 : 10 dilution (vigorously underlined!) with water.

50mL per year, diluted, gently stirred, and the remainder saved for the future. Good luck, whoever needs to find a replacement. Superior bubble fluid is rare stuff.

THIS is how to make a billion bubbles. Do not do this.

Old Electronics

Old stuff, destined for the dump.
A pile of decrepit victory.

In the process of clearing space, you come across all manner of ancient and fascinating things. Desktop computers. Inkjet printers. CRT televisions. Slide projectors. Old motors and control gear to approximate sidereal motion.

Well, okay, reverse sidereal motion. The reason telescope mounts cost more than telescopes, because keeping stars and deep sky objects fixed in the field of view is no small task.

We’ll pop some of these open, gut ’em for any good parts, and move the remainder on to e-recycling. It’s the cycle of e-life!

Hand Riveter

Pop rivet tool.
Orange handles are a nice touch.

Pop rivets haven’t seen much use in the shop of late, but they always remain an option. You put one in the nosepiece of the tool, slide through a pre-drilled hole, and squeeze the handles. That action draws the rod and bead back to the tool, deforming the rivet to compress your materials together as the bead on the far side “pops” off. Can be handy, especially when you can’t access the other side of something easily.

This one was acquired at the tail end of the 1970s, for the not-insignificant sum of $25, or $100.54 today. You can pick up the equivalent tool from McMaster-Carr with delivery tomorrow for $31.25 plus shipping, whatever that tells you about the current state of the economy. Don’t read too much into it.

Etching on rivet tool.
August, ’79. Nice vintage.

Note that the handle has also been etched with “Consumer Bargain,” which is cryptic and delightful. Clearly, this was a steal.
