The Glowing Bottle

Autopause

Materials

1 Empty Jar with Lid
1 Empty Jar with Lid
1 Tube of White Luminol Powder
1 Tube of White Luminol Powder
2 Bottles of Hydrogen Peroxide
2 Bottles of Hydrogen Peroxide
2 Tiny Tubes of Hemin Powder
2 Tiny Tubes of Hemin Powder
1 Tube of Orange Luminol Powder
1 Tube of Orange Luminol Powder

Instructions

STEP 1
0:00

Reach into your kit & pull out the bag with the big bottle with the black cap in it. Place everything around the white mat, and put the bag back in your box.

STEP 2
0:09

Fill the plastic bottle half way with cold water.

STEP 3
0:31

Add the entire tube of white powder. Put the cap back on the bottle and shake it for 5 seconds.

STEP 4
1:02

Upcap the bottle of hydrogen peroxide and gently squeeze in the entire bottle. Put the cap back on the bottle and shake it once again for 5 seconds.

STEP 5
1:38

Turn the lights down so we’ll be able to see it work best.

STEP 6
2:09

Uncap the tiny tube of gray powder and pour it all into your jar. Place the cap back on and give it a final shake to see it glow brightly!
(Dr. Jeff is using a liquid, but your kit contains a powder that works much brighter!)

STEP 7
4:18

To reuse the bottle, simply pour the liquid down the sink and rinse it out.

STEP 8
4:35

Fill the bottle again halfway with cold water.

STEP 9
4:43

This time, add the entire tube of orange powder. Then, recap the bottle and shake it for 5 seconds.

STEP 10
5:13

Uncap and gently squeeze to add the entire bottle of hydrogen peroxide. Then, put the cap back on the bottle and shake it for 5 seconds. 

STEP 11
5:43

Dim the lights once again. The darker the better.

STEP 12
5:56

Take the cap off the tiny tube of gray powder and pour it all into your jar. Place the cap back on and give it a final shake to see it glow brightly!

How It Works

Sometimes when a chemical reaction happens it gives off light. A great example of that is a firefly. They mix chemicals together and it gives off light. In our experiment, we mixed two chemicals together, hydrogen peroxide and another one called luminal, but at first, nothing really happened. Sometimes when you mix chemicals together they react very slowly. To make it glow really bright, we had to make the reaction go faster and to do that we added a catalyst. A catalyst is something that speeds up chemical reactions. It can make it thousands of times faster or even millions of times faster. In this case, it made the reaction happen so fast that it gave off a blue light.

We did the same reaction again, but the second time we added fluorescence which made it green. The catalyst we are using is called Hemin. And it's the exact same chemical found in your blood. Since this catalyst is found in blood this reaction is useful to crime scene investigators. They can spray the liquid that was in our bottle, hydrogen peroxide, and luminal, on the walls, furniture, or anywhere else and it will light up if there’s a catalyst there, aka blood. Blood will be the catalyst that shows up telling the investigators something bad has happened.
