Peanut butter. According to many scientist lava has the consistency of peanut butter.
What a cheap answer, peanut butter can be any number of consistencies based on temperature and is the first reference point for “thick substance”. I need a scientist to experimentally compare the two and fell me if I need gif or skippy and at what temperature and humidity.
Whenever I see videos of them breaking into a fresh stream of it to collect some in a bucket, it looks less viscous than that.
(Maybe I’m just used to the bad peanut butter with the trans fats that keep it from separating, and the natural stuff is thinner?)
This is dangerous information for me as I like peanut butter a lot. Now I must beware the glowing forbidden peanut butter.
