Whippits is just whip-cream hits from a can right? I used to do those by accident when I was little, cause I didn't know it had to be upside down to get the cream out. Its a pretty short high, it definitely not 5 minutes, its like, not even a minute at most. Its really intense though, its fun, if you have some whip cream you might as well try it, I'm pretty sure its not extremely harmful.
