Join me and Katie as we do some engineering and drawing demonstrations! This video includes the Metropolitan Cathedral in Mexico City, which was build on a lake. Get some pens or pencils, paper, kinetic sand, a coaster and a big bowl to join in.

Join me and Katie Hickey to learn more about this structure featured in our book, How Was That Built? In this video we explore the Pantheon in Rome. I do an engineering demonstration to show you how to make a 3D dome, and Katie shows you how to draw it! Get some pens or pencils, card, scissors, split pins and tape, and join in!

Join me and Katie Hickey to explore how The Shard was built! We will do some engineering and drawing demonstrations to explain how triangles are used in structures. Get your pens or pencils, some card, scissors, tape, a hole punch, split pins and some heavy book, and join in!

I read an extract from my book BUILT: The Hidden Stories Behind our Structures. The extract is about Emily Roebling, an amazing engineer from the 19th century who helped ensure that the Brooklyn Bridge got built. Enjoy! Details of how to buy my book are on www.RomaTheEngineer.com There's a podcast episode on Emily on www.BuildingStoriesPodcast.com

Hear about why I wrote my book Built: The hidden stories behind our structures, and what it contains.
