Oahu, Hawaii Dole Pineapple Plantation Demo's are at the top of every hour. You get free pineapples with the demo. I saw two demo's and both cut their pineapple completely different. This is the better version.
(she recommends to rinse the pineapple, it removes some of the acidity making it sweeter and juicier!) I was lucky enough to visit the dole plant when I visited hawaii :)
