A world record for the biggest Coke-Mentos explosion belongs to 1,500 students of Leuven, Belgium. Students, each wearing a blue poncho, added Mentos mints to a bottle of Diet Coke for a simultaneous explosion. familyfancy.com has more than 1500 daily visitors. If it would be possible to bring all of familyfancy.com visitors to one place for a meetup, it would be a good idea to get some Mentos and Coke and break this record.
