When I think a room is looking dull, I go out and buy a new disco ball to spice it up. 
That's cool! How many disco balls do you have?
I have 11, one for each room in my house. I am a big fan of the colorful ones that display seemingly all the colors of the rainbow. 
Yeah the rainbow disco balls are good. Where do you buy your disco balls?
A variety of places, often on Amazon or at Lowe's Home Improvement. Have you ever bought one?
Ah I see. No, I have never. I used to make my own disco balls when I was younger though. Have you tried that?
I have never done that, is it easy to do?
Yeah! You only need a few things like glue, balloons and a few cups. I would recommend it!
I'll definitely check it out. It will probably save me a lot of money since these balls can be expensive. 
How much does a normal disco ball cost to buy now?
The ones I buy range anywhere from about 30 dollars to 100 dollars. 
Yeah that sounds reasonable! Thanks!
