Hula Hoops

We, OK I have been trying to make adult size hula hoops for exercise. I bought what I thought and was told was 3/4 inch irrigation tubing. I kept trying 3/4 inch connectors and they were too small and I couldn't figure out why. Well, today I went out and measured the tubing. Its 1 inch. No wonder the connectors wouldn't work. I will try using the correct connector and see how that works. I am going to give the guy who sold me 3/4 in tubing a hard time next time I see him. LOL
