Making Glow Sticks at Home is Fairly Easy

By Anupum Pant

Glow sticks or Light Sticks are so much fun and assuming you are able to get the required chemicals from a lab supply shop (online or offline), making them at home is as simple as mixing tang.
I came across this interesting video which teaches you how to make glow sticks at home. The best thing: You don’t have to worry about mixing exact measurements. An experiment definitely worth a try!

As the video tells you in the beginning, making these at home will cost you more than a ready-made glow stick. That is because the chemicals required to make it cost much lesser when bought in bulk. Nevertheless, it should be fun to try at home. If you can’t watch it, I’ve mentioned everything in detail below. [video]

1. SOLVENT: The first thing you need is Diethyl Phthalate (DEP). It is a fairly common substance because it is used a lot in detergent, sprays, cosmetics industries. Although it is clear and looks almost like water, you should avoid touching it with bare skin. In fact, none of these chemicals should be touched. Gloves are extremely important here. DEP will be your main solvent. All the magic will happen in it.

2. COLORS: The second part of making glow sticks involves the color. For this, you’ll need something called the fluorescent dyes. The ones used in the video are:

  • 9,10-bis(phenylethynyl)anthracene for Green – Orange in solid state.
  • Rubrene for Yellow – Red in solid state.
  • 9,10-diphenylanthracene for Blue – White in solid state.
  • and Rhodamine B for Red – Green in solid state.
  • Mix the blue and Yellow solutions for the white glow stick.

3. ENERGY: To make enough energy to light it up you’ll need a mixture of three chemicals. The first one is TCPO (DNPO or CPPO can also be used). It is an expensive chemical. It can be made for much cheaper [video] The second chemical is added to keep the liquid in alkaline state. Sodium Acetate (Remember Hot Ice).
In the end, you add, Hydrogen peroxide and shake to give the final glow. It acts as an oxidizing agent, reacts to form an unstable compound, which excites the dye to an excited state. The dye emits light when it comes back to the ground state. This is the reason you need Fluorescent dyes – normal dyes won’t work.

Things You Should Know About Farts

by Anupum Pant

Flatulence, an expulsion of intestinal gas, commonly known as fart, is something no one likes to talk about because it is considered a taboo, almost everywhere in the world. To top it all, some might even sideline this article by tagging it as a vulgar one. In my defense, that is exactly the purpose of my blog – To talk about things no one will talk to you at school (or anywhere else). Our inclination here is to learn.

Avoid shaming others for it.
Firstly, it is important to know that, irrespective or gender, race or nationality, farting is an invariable result of digestion and everyone does it about ten times a day. Even dead people fart. So, by shaming someone for letting it out in an accidentally loud way, is hypocritical on your part; it [shaming others] can be avoided. As Eric Auld says, it is okay to fart.

Do not hold it.
Secondly, it is not okay to hold flatulence to avoid embarrassment. Doing this, has the potential to cause a life threatening condition called diverticulitis. This disease is prevalent among the urban people for obvious reasons. Urban people have a greater societal pressure to hold it, than a free-living farmer. To give you an idea, 30 million Americans are currently suffering from it (old data).

What is it?

Principally, it is a mixture of gases taken in through mouth with food and gases which are produced while digesting food. The composition of ‘gas’ varies with, people, the kind of bacteria in their stomach and the kinds of food they eat. Oftentimes, people don’t hate their own smell; at the same time, detest the gases coming out from others. A fart is comprised of gases like Hydrogen, Nitrogen, Carbon dioxide, Oxygen and Methane. It smells bad due to the presence of Hydrogen Sulfide, Mercaptans and Ammonia. And the presence of inflammable gases like Hydrogen and Methane makes them inflammable.

Farts in a humid environment can seem worse because during such conditions, our sense of smell is enhanced. This is the reason why farts smell worse in a shower.

Minimizing the effect

Although, there is no way you can end this trouble from your life, you can adjust your diet a bit to prevent this from happening in excess. Beans, cauliflower, corn, eggs etc are some foods which are notorious for producing gas in your body. These foods release a relatively greater amount of gas than other foods while getting digested in the intestines. Cutting their intake can help (of course consult your doctor first).

Another way to lower the problem is to prevent the odor from troubling others. This can be done by using products like “odor-proof undies”.

Coughing or suddenly moving your chair could help you to mask the sound.
