Glow Juice .

luminol
3 percent hydrogen peroxide.
2 large mixing bowls .
distilled water
sodium carbonate
copper sulfate pentahydrate


OK, first step: Take half the water—one liter—and add to it the hydrogen peroxide. We're just diluting the peroxide, basically. Set this bowl aside for later.

Now, in the other bowl, dump the rest of the water and 4 grams of sodium carbonate, which helps all the other chemicals mix together better.

Add to the sodium carbonate mixture 0.4 grams of copper sulfate pentahydrate. It’s going to help light up the luminol, which is looking to steal electrons from metals—in this case, the copper in the copper sulfate . Luminol can only dissolve in highly alkaline solutions—11.8 pH.

And now we carefully add 0.2 grams of luminol to the sodium carbonate/copper solution. And here we are with a fully prepped solution, just waiting to glow.

Now let's return to the diluted hydrogen peroxide and add it to the luminol solution. The hydrogen peroxide replaces two of luminol’s nitrogen atoms with oxygen, producing a bunch of electrons so excited that they kick out a blast of photons. That’s the glow in our glowstick!


ps .... dont drink it !


The glow juice was not very hard to prepare. We just had to get two bowl for 2 different solutions. In bowl one we had water and hydrogen peroxide. In bowl two we had  4 grams of sodium carbonate and 0.4 grams of copper sulfate pentahydrate. while demonstrating it , we will have to mix the 2 solutions and put it into one beaker, and mix the third solution we cam up with , with luminol to make it glow.
