Toxic Explodium: Thallium Azide (Dont Try At Home!)
Preparation and detonation of about 3.25 grams of thallium(I) azide. The compound is easily made from thallium(I) nitrate and sodium azide. It is not as sensitive as lead azide but it will still detonate on sudden heating or shock. The explosion produces a cloud of thallium metal particles making the smoke very poisonous.

Death Crystals (Thallium Sulfate) #donttryathome #chemistry #thallium #sulfate #inorganicchemistry
A far superior prep of thallium(I) sulfate than anything I have shown before. Doing it this way dissolves the metal over a couple hours whereas if you just try to dissolve thallium in sulfuric acid it will take several days of heating and stirring.

Phosphorus Selenides & Transition Metal Selenocyanates #phosphorus #selenium #chemistry #experiment
In this video I make up a mixture of phosphorus selenides as I attempt to make phosphorus triselenide. As it was I ended up with three selenides of phosphorus. Next I made up a solution of potassium selenocyanate from selenium and potassium ferrocyanide. Then I precipitate out lead selenocyanate, mercuric selenocyanate, and copper selenocyanate.

New Video: Sodium Telluride From The Elements #sodiummetal #chemistry #telluride #inorganicchemistry
New video. While tinkering with the reaction between sodium and tellurium I stumbled across a way to slow the reaction down and actually produce a decent amount of sodium telluride. Normally this combination of the elements just explodes much like the combination of sodium and sulfur which is the lighter congener of tellurium.
