Neat experiment with honey: it will be attracted to a plastic cup when the cup is electrically charged


Thunderf00t tried to explain why does the water get attracted to a plastic cup when you rub it against your hair. It seems that water behaves like an electrically charged medium and people don’t really know why it does that.

in order to observe these things better Thunderf00t used honey, which contains water, to see how it reacts to an electrically charged cup. And it works. This gift keeps on giving.

Why does water get attracted to the plastic cup in the first place?

CompoundChem mega infusion: chemistry of honey, cosmetics chemistry, antibiotics, insect venoms, aminoacids

The guys at Compound Chem do a great work with their chemistry articles. You don’t need to be a chemistry minor or the sorts to understand what is it about. Once you read what they are posting you are getting one step ahead of crazies that believe that vaccinations are bad or that GMOs will kill you or the sorts.

The infographics from below will teach you way more than you have learned in the high school. Have fun.

1. What is the chemistry of honey. Why won’t it spoil?

Well, honey won’t spoil because it has gluconic acid and hydrogen peroxide and it draws water from its surrounding and killing this way bacteria. Those bacteria being killed honey will not be able to spoil.

2. What chemical compounds can you find in cosmetics?

In lipstick, for example, you can find castor oil, bees wax, lanolin, dyes, perfumes.

3. Organic chemistry: what are benzene derivatives?

Benzene is composed of 6 carbon atoms and each one is connected with a hydrogen atom. Benzene derivatives, where a hydrogen atom is replaced with a functional group are called aromatic compounds as they smell nicely. Example of benzene derivatives: polystyrene, paracetamol.

4. How many antibiotics are there?
Antibiotics are substances used to kill off bacteria. They won’t work on viruses. You need anti-viral stuff for that. Antibiotics were first discovered in 1930 and we now have antibiotic resistant bacteria due to improper use: don’t take antibiotics if you’re cold. Cold is generated by a virus, not a bacteria. Also, if your physician told you to take 20 pills then take them all, not 18 or 19.

5. What is the chemical composition of insect venoms?

Bee venom contains mellitin, apamin, hyaluronidase, mcd peptide, dopamine, histamine, serotonin, phospholipase A, noradrenaline. In order for the bee venom to kill someone you need 2.8 mg/kh of venom in someone’s blood.

6. 20 common amino acids

Amino acids are building blocks of proteins in living beings. From over 500 such substances in the nature the human DNA encodes the genetic information to generate about 20 of these. Essential amino acids need to be taken from the diet while non-essential will be created by our body.
