Footage shows visitors to a science fair turning a crank to set off an elaborate chain reaction that demonstrates mechanical concepts in physics.
The youngsters were playing with the Mouse Trap style exhibition at the National Science and Technology Fair 2021. It is the biggest science and technology event of the year, held alongside National Science Day in Bangkok, Thailand.
The event had the theme ‘Art – Science – Innovation and Creative Economy.’ Visitors could witness the different creative booths at the event, and can also attend an online virtual exhibition if they could not visit the exhibition hall physically.
