Grenadine is always the same flavor, it's called grenadine. Saying "cherry Grenadine" is sort of oxymoronic. Also, why on God's green earth would you do that?!
So there are some roller coasters that are air powered.... they basically strap you in, and then launch you, at 110+ mph, on a track that goes vertical at around 5g's, 400 ft straight up.... then does the 0g hill effect thing... and then plummets you down 400 ft and then airbrakes you back into a standstill. >_> That has nothing on this.
Also that Ferrari coaster in Dubai.
