I will be turning this coil of tubing into these lovely hula hoops! They are made from the finest material called polypropylene, and they are ranging at 5/8 size. My order came form Colorado Hula Hoops on Amazon. It included the slightly smaller tube to connect the ends. Make sure you have the connecting tube! You don't have to use the polypro. Feel free to use which ever tubing you prefer! 

To calculate the size hula hoop you'd like, you take the diameter that you know you want, let's say for instance you want a hula hoop with a diameter of 30 inches. To calculate the circumference of the hula hoop, you're going to need to multiply 30 by pi which is 3.14. You multiply that and it comes to 94.2 inches. To get the feet, you divide it by 12 which is 7.85. To find how many inches exactly the .85 are, you can Google how many inches .85 of a foot is, and it converts it right there in a table for you. My tape measure is only in inches and only goes to 60. So what I did was take the 94.2 and divide in half to get 47.1. I measured that twice around to get a hula hoop with the diameter of 30 inches.

I did at first use a hacksaw to cut this tubing. It's took me quite some time to be able to cut through this tubing with this hacksaw. I learned very quickly that it was not the way for me. I started using a dremel and it cut through way easier. It did leave more choppy ends, but that can be broken off and sanded down. You could also use a pair of tube cutters if you prefer that way.

I noticed I accidentally slid this connector piece a little too far into the one side. I want to be able to have enough space to drill the hole for the snap button, so I just need to wedge it out a little bit. So do just keep that in mind when you are putting these connector pieces on the inside of the tube you don't want it to be too far on one side.

Time to put in the snap button! The snap button has a little bit bigger of a hole than the rivets did. So I definitely worked my way up more with drilling the hole, so that it would be a perfect hole to be able to slide the snap button right in. Drill the hole on the connector tube thats sticking out of the hoop, putting it on the outter side. Slide the button right in, making sure you are lined up with the hole. Go slow, you don't want to slide past the hole as it may be extremely hard to get back out! Then connect the pieces together and make a small hole where the button is so you can drill the hole for the other side, making them able to snap together!
