Depends. Do you have a matching arbitrary generator?
Vegemite has enough salt to be conductive, and is viscous enough to draw distinct traces with on suitable medium (say, toast that has been cooked such that most of the water has evaporated, making it a good insulator), as Luke Weston has ably demonstrated.
I had to look up vegemite since I've never heard of it and I don't think it's available here....although perhaps in a specialty store. Looking over the ingredients on first take it sounds freaking disgusting but I'd probably like it.

Possibly an obtuse question, but a PTC heater should have the same temperature regardless of the environment right? Providing the environment's temperature is lower. Any environmental difference should just contribute to getting to temperature quicker.
A for effort. That’s more impressive than RevK’s ADSL over wet string.
EE prank in future: replace potting compound with vegemite

Heh. I remember getting into an argument with an "armchair engineer" over how important "Arctic Silver" type thermal compounds were. I explained that they just became popular with processors that had a very bad thermal design, like early pentium-xx with the bare core exposed. Later designs that had a proper envelope with sufficient covalent area didn't need it, even under duress.
I explained that with a properly designed component that had adequate covalent area, what was more important was stability of formula and manufacturing process of the paste. I proved my point by replacing the thermal paste on a P4 with peanut butter, and overclocking it to 3GHz. It got a few degrees warmer than with the arctic silver then stabilized and was quite happy. Now if we'd left it that way long enough to cook away all the oil in the PB, things would've gotten hairy... but it made the whole shop smell like Christmas baking.
@bd - I've been using Silicone Self-fusing Tape to seal up outdoor connections for decades; ever since my teenage years doing DirecTV/Hughes satellite TV installs. Stuff is effing magic for sealing against weather, though the claims of it holding against pressure are greatly exaggerated.

*Tool-Dwagon-ily*Yes that tape is really something else I have used it before

We sort of 'borrowed' Marmite as the basis for Vegemite both are yeast poo and used to be made from brewery leftovers
After much sleuthing I have managed to get my hands on a Tektronix 2235 multiplier (and half a dead 2235) for the price of a crate of strongbow (£12 at the moment). Unfortunately won’t get it until around mid January as the owner is in the US until then and doesn’t trust his wife not to give me one of the good scopes by accident
Edit: well that's depressing. It's a "max £1 fees" day on ebay today, 10pm here and literally nothing interesting has been listed.
Heres an interesting thought experiment, which would you lot prefer? A 6236B HP power supply or a TM506 with a PS503A. The tek doing the same thing but with higher current. Electrically speaking, factors like space occupied non relevant, which is better?
Then again there is the factor that i have lots of hp in rack and no tek in there... yes i, of course, realize the one true solution would be to pick both but lets just assume both together are impractical.

home brewed a tripler once for that monster Dumont solid state "porta scope".
really only did it just to see if it was possible. worked great. lots of space in that old Dumont though.
100x voltage divider and my carefully ground referenced 3466a said 10.9 Kv vs the 12Kv in the manual. meh. expected that bathtub seal to arc....but it never did.
sometimes stuff works and surprises ya'.
As an English person I would point the Americans in the direction of Baconaise and Twinkies, while I sit here smugly forgetting we invented marmite which is basically yeast poop.
