A highlight of Dubai's Big 5 trade fair were product demonstrations, some inviting audience participation
A peeling contest showed that a leak sealing membrane could not be removed once applied. Visitors to a decorative concrete demo watched an artist use a stencil, black paint and some fancy brushwork to apply a design with a slightly weathered look to a bench. Another company offered fairgoers panoramic views and a chance to take selfies from an elevated boom lift platform. In the excavator challenge, contestants at the controls of a compact loader tried to pick a basketball off a cone and drop it in a bucket.
