Weighted Hula Hoop - calories burned ?

Does anyone know a good estimate for how many calories a weighted hula hoop session burns, I am buying one today and want to track this in my exercise diary, thanks.

of all the homework i've done, i've gotten that you could burn up to 300 calories in 30 minutes, i'm not a pro, but i can keep it off the ground and i find it hard to believe that i have burned 300 calories. i too am having trouble finding out how much i burn, and a heart rate monitor is just too gosh dang expensive!
