We bought this for a party along with the spinner motor which I think you need. It creates a great effect and is well worth the money. You do need to make sure you have a strong light source to point at it though for maximum effect. Amazon sell one but I didn't get it after it was critisized by a reviewer so I found one elsewhere. I would give it 5 stars if the whole thing came as a package instead of having to buy separately.(Also a 'D' battery for the motor is not included.)
