In this video from <i>Periodic Videos</i> we look at aspirin, show you an old sample and make a new one.

In this video from <i>Periodic Videos</i> we join a group of John Moses chemists as they climb Mount Snowdon and synthesis the anti-cancer drug Cisplatinum (or Cisplatin) in a small tent at the summit.

In this video from <i>Periodic Videos</i> The Professor discusses new research suggesting why gold (among other dense metals) is found close to the Earth's surface.

In this video from <i>Periodic Videos</i> The Professor overcomes his fear of heights to tell you about concrete.

In this video from <i>Periodic Videos</i> we look at the reaction of Caesium in Water.<p>The reaction is 2Cs + 2H2O → 2CsOH + H2. However, the H2 can then react with O2 in the air to explode. Also, unlike the other alkali metals, except perhaps Francium, Cs is a liquid just above room temperature so the initial heat of reaction will melt the metal and one has liquid metal reacting with the water.</p>

In this video from <i>Periodic Videos</i> we look at the FIFA World Cup Trophy and why if it is made of solid gold the trophy must be hollow. We also look at its distinctive green stripes, made of an interesting compound called malachite.

In this video from <i>Periodic Videos</i> we look at the famous Buckminsterfullerene, better known as buckyball or C60.

In this video from <i>Periodic Videos</i> we discuss blood - both real and fake - includes an explanation about haemoglobin.

Dmitri Mendeleev's business card is among the many treasures in the archives of the Royal Society. Professor Martyn Poliakoff explains.

In this video from <i>Periodic Videos</i> the Professor discusses graphene as two UK-based scientists win the Physics Nobel Prize for its discovery.

In this video from <i>Periodic Videos</i> we meet a teacher who uses our videos in class - and then he showed us a cool experiment.

In this video from <i>Periodic Videos</i> we look at the reaction of Fluorine Gas and Sulfur.<p><i>NOTE FROM THE PROFESSOR:</i> This is a very violent reaction so many things may be going on. In the molecular structure of solid sulfur, one finds S8 rings. At the simplest level, these react to form SF6; S8 + 48F2 → 8SF6. However, this reaction is involves a jet of F2 gas so there may not be enough fluorine and some SF4 may be formed. SF4 can react violently with water in the air to form SO2 and HF.</p>
