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. Take everything out of the bag and place it around the white mat that is also included in your box. Then, place the empty bag back in your box.

STEP 2
0:09

Take the plastic bottle and place it in the middle of the mat. Next, add water and fill up half of the bottle.

STEP 3
0:31

Add the entire tube of white powder. Put the cap back on the bottle and give it a shake to mix it all together. Just about 5 seconds.

STEP 4
1:02

Next, take the black cap back off and grab the bottle of hydrogen peroxide. Uncap and gently squeeze to add the entire bottle. Then we’ll put the black cap back on and shake it to mix it once again.

STEP 5
1:38

Now we’re ready to make a chemical reaction! Once we add the last ingredient it will happen. Before we do, let’s turn the lights down so we’ll be able to see it work best.

STEP 6
2:09

Take the cap off the tiny tube of gray powder and pour it all into your jar. Place the black 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

Now, let’s try making another color! We included a second packet of materials inside your box. To reuse the bottle, simply pour the liquid down the sink and rinse it out.

STEP 8
4:35

Let’s use the same process as before. First, we want to fill the bottle halfway with water.

STEP 9
4:43

Next, we’re going to add the powder. Just like last time, except this time it’s orange. Then, we’ll recap the bottle and shake it so the powder dissolves.

STEP 10
5:13

Let’s take the black cap back off again and grab the bottle of hydrogen peroxide. Uncap and gently squeeze to add the entire bottle. Then we’ll put the black cap back on and shake it to mix it once again. 

STEP 11
5:43

Now we’re ready to dim the lights again, and then we can add our final catalyst ingredient to make the reaction go super fast. 

STEP 12
5:56

Take the cap off the tiny tube of gray powder and pour it all into your jar. Place the black 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 fireflies. 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, very slowly. You might be able to see the faintest glow if all the lights were off, so to make it glow really bright we need to make the reaction go faster, and to do that we add 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. It’s made inside our bodies. 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.
