Dance parties are not complete without a disco dance floor. Fortunately, you can build one with a few hours of work by following the steps below. All you need is some hardware, old or unused CDs, and strobe lights to create the effect of a 1970's disco party, and your guests will be able to dance the night away.
Take your four plywood pieces and place them together to form a square. You will see a cross in the center of your square. Carpet tape the seems of the cross, bringing your squares together. Remember to not double tape the center of the cross (tape over the tape) or you will have a bulge in center. Now hasp each end of the cross locking the squares together.
Nail your plywood square onto your roll of foam. Make sure your nails are no longer than the thickness of the plywood and foam combined or your nails will scrape the floor. The foam is used to create a barrier between the floor and your plywood, this way the plywood won't scrape the floor. It also provides some padding for your guests.
Paint the top of your plywood square black, and then let the paint dry.
Take your old or unused CD's and superglue them face down so the shiny side of the CD is facing up. You're doing this to create a reflective surface so that the lights will bounce off of your dance floor. Let your CD's dry onto the plywood.
Screw your Plexiglas into the plywood over the CDs that you just glued down. This will prevent your CD's from breaking while people are dancing on your dance floor. The Plexiglas is also flexible and durable. You want to screw in your screws every six inches to ensure that the Plexiglas will stay attached. Don't forget to add a screw in the center of each Plexiglas square, otherwise, it will bow in the middle and people will trip. You are using counter sink screws because they don't stick out and won't trip anyone.
Take your rubber trim and trim around your whole dance floor. You are doing this for a few reasons. One, it will cover the screw tops so people don't see them. Two, it will create a seamless edge for your guests to walk up on. You have three levels of dance floor. The trim will bring the whole thing together so people don't see all the layers, just the dance floor you've created. There are two ways of applying the rubber trim. One, you can buy self-adhesive trim. Or, you can use epoxy putty to adhere the trim to your layers.
Place the four strobe lights at each corner of your dance floor facing the center of the dance floor. Strobe lights have controls that let you choose how fast the strobe is. Set the strobes at different intensities. As the strobe lights hit the floor, they will light up the CDs and your whole dance floor will have lights dancing all over it.
