Oncle Sam Popcorn Machine: changing the popcorn experience, one kernel at a time. As part of ECAL’s “Low-Tech Factory” exhibition that celebrates the process of product creation – a counterargument to mass-production – three students developed a contraption that pops kernels of corn one by one. The set-up appears as if it belongs in a chemistry lab; as a kernel is released from one side, a perfect pinch of salt is deposited as well, both falling into a puddle of oil heated by a tealight. Then, magic happens as a kernel transforms into a fluffy piece of deliciousness. Indeed, Oncle Sam makes the “pop” in popcorn the star of the show.
