Fun rolling like a Hamster in A Ball (zorbing)

Woo, I last saw this in 1990s Jackie Chan's film but never thought this is real. Roll like a Hamster down the hill!












What: Zorbing (roll like a hamster in a ball!)
Who: www.zovbsg.com /www.adventour.com.sg
Where: Old Holland Road

Rates: Zovbsg offers 50 dollars for 2 rolls down the hill
35 dollars for students and children

Adventour offers 50 dollars for 2 roll down.

Verdict:
Ok, I've made some enquiries with the people there and they've mention that the slope is gentle and inclined @ around 20-25 degrees and hence require some pushing at the top for the ball to roll.

How fun is it to roll like ball and then climb back up like a hamster? I leave it to you guys to decide man. Remember, reinvent and have fun with your weekends =)

P.s please don't flame me if you all think this is an ridiculous thing to do. Remember I'll give ideas of interesting activities to do and everyone's opinions differ.
