Hi, I just got these items for my birthday—what do you think? And here is my collection of 55 absolutely stunning pieces 🤩; which one is your favorite? I’m curious to hear your thoughts.
Salut, depuis 2–3 mois j’ai un noyau de mangue 🥭 qui pousse, mais au moment où la tige sortait, la racine s’est soulevée du bocal rempli d’eau, a séché et s’est cassée. J’ai pensé qu’il allait mourir, mais non, il a même fait sortir des feuilles. Je me demande quoi faire maintenant ?
Hi, I'm interested in radioactivity detection, which is a really cool hobby, but I don't know which radiocode model to get. I was wondering if you had any advice.
​
PS: I already have a Geiger counter, but it's a cheap, inaccurate model, so I'd like to invest in a proper one.
Thanks
Hi, I was wondering how dangerous this ~12g thallium cube (an incredible sample) is?
Hello fellow collectors, I was wondering what to expect in terms of the appearance of this white phosphorus cube sold by NovaElement?
Here is my thallium, there is about 100mg of it, and I was wondering if it is used in chemistry?
