does this really work

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!

does it work...have u tried it

No I have not... but obviously neon high lighters do glow under black light. Raves and such.

Clever! :D

Just not gonna be eddible.

brown colour does not appear... wat to do... need urgent help pls

how hot does water have to be, because i put the kettle on and i stopped it half way so the water wouldn't be boiling. I put the water into the boal with the chopped potatoes and the colour went really light brown. It's see through, so would it still work

How long do you have to stir it? And when I did stir it, the water stayed clearish,not brown. I'm I doing something wrong? Help.

how much potatos you use for making this magic mud

MrE1 year ago

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.
