Gender ultrasound

Madison • Baby Boy making his way to June 3, 2016 ❥ madly in love with his daddy ❥ blessed.
Tomorrow's the big day!!!! The boyfriend, my mother and I are going to my ultrasound to find out the gender of our baby!! I'm so excited I feel like a kid on Christmas, but I'm really hoping the baby won't be stubborn and we can figure out the gender for sure and not have to wait for another month. 
A friend told me that drinking some orange or Apple juice an hour before the appointment will help make the baby more active so there's a better chance of seeing their genitals. Has anybody else been told or knows of any silly ways to make the baby more active for an ultrasound?
