Aine, a Year 5 student was the winner of her year group. Aine proved that it is possible to weigh smoke! Aine thought that you could weigh smoke by burning 20 cigarettes without filters and subtracting the weight of the remaining ash from the weight of the cigarettes before they were burnt. Aine was very precise with her measurement and even conducted her experiment with very very sensitive scales (the ones real scientists use!) So there you have it, yes you can actually weigh smoke!
