Engineer Roma Agrawal uses surprising materials to explore some whacky engineering challenges
About this Event

As an engineer on The Shard, an iconic London landmark, Roma Agrawal knows that steel and concrete are master materials for big pieces of a structure.

But what happens when you throw all sense out the window, and use completely the wrong material to build stuff? For example, what about using gummy bears to make swimming pools? Meringue to make rocket insulation? Or even chocolate to make a bridge?
Through these whacky combinations, Roma reveals the secrets of how materials work, and why engineers don’t normally attempt such stunts and stick the materials they know and love.

This is a theatre event for children and adults to enjoy together. We recommend our family talks for children aged 7–13, though they can be enjoyed by audiences of all ages.

All young people under the age of 13 need to be accompanied by a paying adult and those aged 4 and above need a ticket to attend.
