Alex Russell has been crowned winner of ICE South West's Pitch 200 regional heat using layers of cereal and a drill as props to demonstrate pavement engineering.
Last week's heat in Bristol saw Alex explain that brittle cornflakes make far rockier roads than oats and granola. His props included two large transparent containers containing rocky road and different types of cereal. He drilled into both to show how the more compact cereals were not significantly damaged, whereas the more brittle concoction ended up sprayed over the floor.
There were other entertaining presentations: Kevin O'Donoghue presented entirely in rhyme while James Foreman used tiramisu in a cafetiere to help demonstrate soil behaviour.
Alex Crump explained how "today's civil engineers have our future in our hands", while Katy Toms stretched high to turn herself into the 'H' on Plymouth's helipad while Peter Radford purposely fell off his homemade arch bridge. Melvin Wood declared his love of rivers with a topical t-shirt and a Valentine's poem.
The evening was hosted by BBC Points West Business Correspondent Dave Harvey.
Alex Russell will now be ICE South West's regional ambassador for 2019 and will take his winning rocky roads presentation to London for the final later this year.
