THE MAGIC DOUGH

         So this is a very interesting experiment to do. Basically we have dough which glows in the dark and  you can make it using only the things available in local shops. The dough has a texture like a pizza dough, when we apply force it absorbs it and falls like thick fluid when held in air.

MATERIALS REQUIRED

• Potatoes.
• Tonic water or a glowing fluid like highlighter ink.
• Some bowls.
• A jar.

PROCEDURE

• First chop the potatoes finely and soak them in water for few minutes .
• Strain out the water and leave it for 10 to 15 minutes.
• A separate layer of white fluid (starch) settles at the bottom. Pour out the remaining water and again leave it undisturbed.
• More of waste water is separated pour it out into some other container , don't think it'll be useful in any case.

 Now you from here on there are alternative procedures:-

CASE : 1 (USING TONIC WATER) 

• Leave the dough for 2 to 3 days to drive up.
• Then if you want to make the dough mix the power with the tonic water.

Note : You can even destarch the potato directly using tonic water instead of drying the starch to powder and again making a dough using tonic water.

CASE : 2 (USING HIGHLIGHTER INK)

• Dry the dough to powder for 2 to 3 days.
• Dilute the ink of highlighter in water and you can mix the powder with it.

CONCLUSION :-

The one made with highlighter glows in darkness and the tonic water one glows only in UV light or black light.
