Chemistry experiments that you’d want to perform

The diet coke and mentos experiment.

The diet coke and mentos experiment.

Very often, people forget that not only can studying chemistry be fun, teaching it can be too. Teachers who employ various aids to teach chemistry or for that matter any subject, have been found to receive better feedback from students in general. To make learning chemistry fun, it is the duty of a teacher to show students how chemistry can be fun. And what better way to do this than fun experiments? Like your teacher we believe that chemistry can be fun too. Here we describe 3 basic experiments that might help you see how much fun chemistry can be!

The moth balls and soda experiment.
Drop a few moth balls in a jarful of soda water or any aerated soft drink. What do you see? You’ll notice that the moth balls bob up and down in the water. They’ll do this for quite some time if you keep the jar closed. This happens because as the moth balls sink, they gather carbon-di-oxide bubbles on their surface and rise to the surface. When they come to the top, the gas bubbles burst and the moth balls sink again.

The diet coke and mentos experiment.
Be careful with this one! Do not do this indoors. So what we’re looking at creating here is a diet coke volcano. Place a funnel or something over a jar full of diet coke. Put a few tablets of mentos in this funnel and run for your life! A huge, very high volcanic eruption of diet coke takes place! What happens is that the mentos has incisions all over it and this leads to a large surface are. CO2 present in the coke occupies these areas causing it to come gushing out all at once.

The invisible ink experiment.
Baffle your friends by passing around notes written in invisible ink! For this you’ll need a couple of lemons, a pen and some water. Squeeze out all juice from the lemons. Mix an equal amount of water to this extract. Flush out all the ink from an ink pen and fill it with the liquid you created. Use it to write stuff on paper. Let it dry. The writing vanishes! To read the writing hold it near a soft heat source like a light bulb, or near a fireplace. Lemon juice on mild heating gets oxidized to a brown substance that can be read easily.

    Can you please post the video of mentos & coca-cola experiment? I would like to see the video.
