Eggsperiment

Greetings fellow Scientists!

Meet the star of our today's session:

We conducted two EGGsperiments:

In the first one, we answered the following question: What are egg shells made of? Crushed egg shells were reacted with hydrochloric acid. The gas released was passed through limewater which turned milky/cloudy (carbon dioxide was released).
Egg shells are made out calcium carbonate.

The second EGGsperiment aimed at measuring how much gas can be released in this reaction:

We also set up an experiment where the whole raw egg was immersed in hydrochloric acid:

Update soon as this experiment requires time :)

Glowing magic mud

Greetings fellow Scientists!

Today we made non-Newtonian liquid that can glow in the UV light.

Equipment used:

We started by extracting the starch:

Then, we added some tonic water with quinine:

After that the fun started!

 

If you would like to do this at home, here is the video with detailed instructions:

Stained glass sugar - quick update

Greetings fellow Scientists!

Quick update about our stained glass sugar experiment. This is the final outcome:

As you can see it turned out very pretty.
