diet coke and mentos

diet coke is carbonated by dissolving carbon dioxide gas in it

the CO2 usually returns to gas fairly slowly, but faster when there are more nucleation sites - for example, dust or rough surfaces

(this is why the first bubbles of boiling happen at fixed points on a surface of a pot - those are nucleation points)

the surface of mentos is very rough

and so much gas is created after a mento is dropped in that soda erupts from the bottle

@packbat fun Many history about why i said i have participated in this:

carbonated water and koolaid packets do the same thing

@manifold oh dang, I remember that story! 🌋

- 🎒

@manifold I wonder if mixing koolaid and then paper-filtering the resultant liquid would make it safely carbonatable

@packbat @manifold A paper filter wouldn't recover the flavorant, you'd need to evaporate the water out. unless you're talking about removing stray flavor powder and then using a sodastream, which shouldn't be a concern; there won't be enough undissolved stuff to cause any problems
