Collapsible Hula Hoop

Step 3 Insert connectors

Use the heat gun or hair dryer to heat up one of the tube ends.  Move the gun around constantly so you don't melt the tubing.  Once its good and warm, slide the connector halfway into the tubing. I've found that its easiest to get the connectors in by pressing the end onto a hard surface such as a workbench instead of trying to use just my hands.

Repeat for the other end of the hoop half. Your project should look like the second picture below.

Join the hoop halves together, inserting the other halves of the connectors into the empty tube ends.  It should look like a plain black hula hoop when you're done this step.
