After the storming success of his family-friendly talk at the Ri, Andrew Szydlo returns to take us through the fantastic world of steel and iron.

This demonstration-packed performance features spectacular white hot reactions, crazy colour changes, welding, angle grinders, gunpowder, 8 pence coins and a working car engine!

Andrew Szydlo is a chemist and secondary school teacher at Highgate School, well-loved by pupils and Ri attendees alike. He has given public lectures around the country, been featured on TV shows and has become a popular part of the Ri Channel in the last year.
