due to a momentary lapse of reason whilst on eBay, browsing the 'lab glassware' section
I am now the bemused owner of a fairly large glass tube;
(I suspect that it may be borosilicate as there is no green tinge and it is not very heavy, I intend to measure its density)
1207mm long, 160mm i.d., 5.33mm wall thickness. 24 litres capacity (47.5" long, 6.3" i.d., 0.21" thick walls)
It deserves to be in use and on display. I am looking for inspirational ideas ....
So far I have considered, Van der Graaf Generator with belt or hot/dry air
Bi-polar Tesla coil, (Electronics is my main hobby)
Indoor water feature/lamp (Lava, Bubble, Vortex etc.) and some other dumb ideas.
Can anyone suggest a good use for this tube as part of some chemistry related equipment ?

Maybe something like this although your tube has a wide diameter for it's length it might be tricky. I've had some of those lapses of reason on ebay
too.

Noise from an unsteady flame Note how a simple wire loop triggers the effect. I read an account where a very large rijke tube was purring quietly in a
classroom only to be set into a deafening roar rattling chalkboards by striking a tuning fork of a specific frequency from clear across the room.

Very interesting phenomenon and videos, thanks
I may have a quick try
but it would get annoying really quickly!

If you can stand it on end and make the (now) bottom water tight you could have a nice big visible water vortex by placing a big magnetic stirrer at
the bottom.

Barking Dog reaction?

I immediately thought of barking dog, but the tube is very wide. Probably much too wide to be safe.

1. Use it to cover a giant Jacob's ladder.
2. Build a giant cathode ray tube in it. Slide in a homemade hot-cathode electron gun, attach a phosphor-coated glass plate to the end, crank up the
voltage and play with the electron beam. You could make focusing and control coils and eventually be able to display waveforms and stuff.
3. With a good choice of target and enough voltage, you could make a powerful x-ray tube.
4. Using some long skinny electrodes, you could make one heck of an electrolysis cell out of it. Make bromates, chlorates, bromine, metal oxides. Gold
plate a walking stick.
5. Use the Jacob's ladder from #1 to make a NO2 generator, get a Birkeland-Eyde nitric acid generator going.

Maybe I'm dating myself but I think the Lava Lamp idea is great.
Move to Colorado, buy a Sitar and your set for life.

I had considered a Lava Lamp but decided it would be such a project that Id never finish it.
Thanks for all of the ideas, I'm going to consider the 'Birkeland-Eyde nitric acid generator', ... in stages.
