This magical glowing mixture is very strange, because it handles like pizza dough, but the instant you stop moving, it liquifies and melts into a glowing goo.

In this project you'll see how to turn your ordinary garden potatoes, into a fluorescent magical mud.

Step 3:

Picture of

Get started by grabbing a big bag of potatoes, and wash the outsides so they're all nice and clean.

Now chop your potatoes as small as possible using a food processor or any other method.

When you've got your potatoes reduced to tiny bits, slide them all into a large mixing bowl, and pour in enough hot water to cover them completely.

Now just stir this around for a few minutes and don't let the water stand still. You may have noticed the water turning red, and that's completely normal.

Now grab a strainer and another large bowl, and separate the potato water from the chunks, then watch closely as something incredible begins to happen.

how much potatos you use for making this magic mud

You could make this a lot, lot, lot simpler by just buying some corn starch or either potato starch directly from the store. It does not matter what use Starch is Starch. Then just take over from adding the seltzer water. But i can see if you have some potatoes going bad this would do okay.

This is EPIC

misuse of the word epic but ok kiddo

Oh do explain ye old grammar nazi

Awesome! I'll be trying it out... But I'll peel the skin so the solid residue is eatable.

Ah yes a Starch Based Non-Newtonian Fluid, very cool.

You are the best, king. Always enjoy your posts. Keep'em coming.

refreshingly different take on the cornstarch moon mud, interesting that tonic water glows in the dark

You could purchase a highlighter pens for neon green, pink and other colors. Break it open and put little amount in and it would have different colours? Just an idea!

Clever! :D

Just not gonna be eddible.
