If you use the defraction glasses over the 3D glasses and get about 20 feet away from someone they will become Translucent! If you hang the tapestry from your Canopy and you shine the green lasers on someone walking in front of the the tapestry you will be able to see the tapestry through them while they look like they are made of green stars! It's pretty amazing! Also the tapestry had a great 3D effect!

worked great last year, 120 bucks at Lowes
and a USB charging station to go with
I got this one at least 5 years ago...maybe 8.
I love it but have replaced the internal battery twice. Cost was around $30 for each new battery. It lives in the back of my truck, which is kept in front of my Texas home. The weather takes it's toll on these.
This has a wall charger that will cut off once it is topped off. You can charge by cigarette adapter but will over charge if left on. No auto cut off. I do not use that option. The charge last for months on end. If I were being totally honest if I were to charge it every other month then maybe I would not have had to replace the battery twice.
