I made a 1:7 scale model of a Bugatti Chiron car from 15,500 matches, then lit it on fire. It took me 120 hours over the course of 3 weeks to build the car from scratch. 15,500 matchsticks were used and the total weight of just the matchsticks used was 7lbs. I used 49 individual packs, 1.6lbs of glue. The total weight of the completed matchstick car was around 9lbs with dimensions of 23' long, 10' wide, and 7' tall.
