@Sheril@mastodon.social Wow, this is new to me, thanks for the info. I was only aware of the phrase "to give a pitch" ie. declaring/explaining something before this.

@Sheril@mastodon.social cool! I was just reading about this (again) recently. I visit its Wikipedia page too often 😅

@Sheril@mastodon.social Love this. I've mucked around with pine rosin myself which I believe is similar, mixing it with varying amounts of vegetable oil lets you tune the viscosity. Haven't yet found a use for this knowledge yet but it was fun. edit: actually, I did find something possibly useful: storing this stuff is annoying because it sticks to its container real well. To avoid this you can store it in a jar filled with very salty water, it sinks in plain water but if you increase the density it floats.

@Sheril@mastodon.social someone should do the snap tech-expo version of the same demonstration, sped up by the simple expedient of heating the pitch a little

@Sheril@mastodon.social 🤩 The Queensland experiment is great, and the way they still keep an active eye on it may give it the crown. But there are older versions of this experiment made by Lord Kelvin in Glasgow University, although in most pitch is now so oxidized that it can't actually flow. Arguably the oldest functioning experiment is another Kelvin one: a giant diffusion column built into a room in 1870s..
