Great Experiments!

Thanks Koen! I know the letters are too small to read... next video will have bigger letters. If you are interested, Merck order code for formaldehyde solution 37% w/10% methanol stabilizer for analysis is 1.04003.2500 and costs here, in Greece, about 20 euros (2500ml). If you buy it make sure the bottle is always closed tightly especially if you keep it in your room. It is deadly toxic and irritant. On my next video, I intend to synthesize aspirin or something like that.
Greetings, Anestis.

Just uploaded the first video! It seems nice to me. Have a look and tell me your opinion. (The aspirin box says "aspirin" in Greek :-D)

When you have some time, post me a comment on my new channel. Thanks, Anestis.

I also started since about 10 years old being interested in chemistry, physics, nuclear physics and electronics! Now I'm sure about what I want to study ;-) and that is chemistry and nuclear physics of course!... I'm doing experiments every day and I spent all my money on reagents :-D but unfortunately I haven't uploaded any videos yet. I will upload my first video this week, about "Marquis Reagent" and detection of amphetamines, methamphetamines, drugs and aspirin.

Are you really 15 years old? I'm really happy to find someone who is interested in chemistry. I'm 14 years old. :-D Great work!!! I intend to upload some chemistry videos too, but I don't find the required time to do so... By the way, my name is Anestis. What's yours?
