1. Staying with the theatrical theme of our Rock Star video, Lycopodium powder is popular among performance artists and magic acts – for reasons you can probably discern. It's made from the dried spores of clubmoss, which have a very high fat content. Although you'd find a pile of it difficult to light, they're extremely flammable when dispersed and surrounded by oxygen. Good fun for all the family, if not so much for plants.

  2. Calcium oxide – better known as quicklime – glows intensely bright when heated, making it a perfect spotlight. So if you fancy a bit of the limelight yourself, why not emulate the actors and performers of old, who used this technique in theatres and music halls to pick out individuals on stage. It’s rather lovely really. Join the discussion... @touchpress facebook.com/touchpressapps

  3. You just can’t trust the Touch Pressers when they give you a spoon for your coffee. Field’s metal, an alloy, may be cast to make nice cutlery and feels solid in your hand, but it melts at 144 °F (62 °C) – just about the temperature of the water in this glass. It’s a combination of indium, tin and bismuth, which is, incidentally, one of the prettiest elements. Keep an eye out for the next weird and wonderful science video! @touchpress facebook.com/touchpressapps

  4. You can make art by trapping lightening! Charging this acrylic sheet with lots of volts traps a buzzing excited nest of electrons inside. A sharp tap to the top of the glass forces them out, leaving behind channels in the glass where they made their exit. Beautiful and fascinating. Elements author Theodore Gray explains how to do it yourself at popsci.com/diy/article/2008-02/trap-lightning-block.

  5. Deep fried turkey can be delicious but you don't want to add a wet turkey to hot oil, and here's why: watch what happens when Theodore Gray dips a defrosting turkey into very hot oil.

    It is simple chemistry. To see more chemistry in action — sodium being thrown in a lake, a cannonball being dropped into liquid mercury — or if you just want to see things explode, download Touch Press' app, Elements in Action.
