I just got my USA juices and I got cool carts to go with them. I'm having trouble filling them. The liquid doesn't want to sink in AT ALL. I used the taryn spin method, but only got half the amount of liquid I should have been able to get in the cart. When I put the liquid in it just sat there until I spun it and then I could see it at the bottom of the condom (it didn't come with the buttplug kind). Anyone else have this problem?
