Spuitshow: Cola & Menthos hobby

Cola en Mentos spuitshow Cola? Lekker. Mentos. Ook lekker! Cola en Mentos? Lekker, maar ook mooi!

Je weet niet wat er gebeurd wanneer je Cola en Mentos bij elkaar doet? Ah, dan heb je nog even een inleiding in dit onderwerp nodig. Check deze site voor wat filmpjes.

Inmiddels bekend met het fenomeen? Check wat er gebeurd als je het wat grootser aanpakt; laten we zeggen 200 liter Cola en 500 Mentos. Awesome gewoon! (Met geluid aan leuker.)

Waarom Mentos en Cola in vredesnaam zo heftig reageren? Ik heb het voor je opgezocht:

"The primary cause is physical, not chemical. Their explanation: nucleation sites. If you have a liquid that is supersaturated with gas (like soda, which is pumped full of carbon dioxide), a nucleation site is a place where the gas is able to form bubbles. Nucleation sites can be scratches on a surface or specks of dust – anywhere that you have a high surface area in a very small volume. That’s where bubbles can form.

Mentos seem to be loaded with nucleation sites. In other words, there are so many microscopic nooks and crannies on the surface of a Mento that an incredible number of bubbles will form when you drop it in a bottle of soda. Since the Mentos are also heavy enough to sink, they react with the soda all the way to the bottom. The escaping bubbles quickly turn into a raging foam, and the pressure builds dramatically. Before you know it, you’ve got a big geyser happening!"


Have some fun!
