Try investigating drop time vs. temperature, type of oil , measurement, mass or density of ball, width of column. This can be very messy; oil is such a pain to scrub up you’re probably used to having someone else clean up for you.

You’ll need to calculate resistivity so measure the diameter of the wire with a micrometer in several locations (does it vary?). Hmmm – that is turning out to be way more interesting than first thought. It is vitally important that motor oil would not get too skinny in summer nor too thick in winter in any other case the automotive engine would possibly seize. A Falling Ball Viscometer uses the rate of descent of a ball bearing to measure the viscosity of a liquid.

So don’t be surprised if your teacher appears reluctant and suggests you utilize honey. The very first thing you need to learn is about Stokes’ Law and the variables within. You may have cylinders but you can produce H2 and CO2 by response ; let some liquid nitrogen evaporate .

Remember that balloon fuel is not only helium – it has 3% air mixed in with it. The main level is that the regulation holds for ideal gases but at atmospheric pressure and room temperature they will not be that ideal. And is the deviation from ideality depending on the molar mass of the gas, or whether or not it’s polar or non-polar, and the place on earth do you get a polar fuel from ?

Perhaps you can place the wire in water to maintain it cool but then it may contact itself and give a ‘short’ circuit. How would you forestall this; maybe with masking tape, possibly winding it on to a plastic rod so the turns don’t touch.
