Pedantry is fact checking a comment, figuring out it would actually take around a cup (or 1/4 liter) of gasoline, then figuring out how to convert that to drops and pointing out it would actually take close to 4,700 drops, not just a few.

Smart-assery is replying how it can still be consumed as just a single, very large drop.

Smart-assery is replying that gasoline doesn’t have enough surface tension to form such a large drop.

Lemmy-ing is recreating a typical Reddit thread but making sure every comment points out that they’re self-aware.

What if you put it in a balloon and pop it into a funnel aimed into your mouth and you have no gag reflex?

Hmmm let’s see, you need roughly 2.39kcal or 10kJ of fuel a day.

Gasoline has an energy density of 45 MJ/kg.

https://energyeducation.ca/encyclopedia/Energy_density

Sciencing those together means you need 0.00022 kg or 0.22g of gasoline a day

Gasoline has a mass density of 0.7475 g/cm^3, more sciencing means you need 0.294 cm^3 of gasoline by volume.

https://www.engineeringtoolbox.com/fuels-densities-specific-volumes-d_166.html (average across range and convert to g/cm^3)

Here let’s pull a number out of our butts, let’s say a drop is a sphere with a diameter of 5mm, so the radius is 0.25cm. Volume is 4/3 pi r^3 which comes out to 0.065 cm^3/ drop.

0.294/0.065 gives 4.5 drops.

So you’d need 5 drops of gasoline to get your days worth of energy.

Seems we’re off by a factor of a thousand. Most likely you doubled up on 1Calorie = 1000 calories. (Damnit food industry, what the hell?!?) 1kcal is already converted to the base calorie, as opposed to 1kCal.

big Calories are conventionally uppercase, while small calories are conventionally lowercase. So 1 Calorie = 1000 calories = 1 kcal.

Stupid naming system, I know.

https://www.ncbi.nlm.nih.gov/books/NBK234938/#:~:text=For men of reference body,women%2C it is 2%2C200 kcal.

For men of reference body size, the average allowance is 2,900 kcal/day; for women, it is 2,200 kcal.

You are correct!
