The only questions I got were from UK tabloids so you’re in the small group that have asked about it. If your tree is not up already, you will want to shape the top into a dome. For mine, we lost a good foot off the top using hedge trimmers - just sort of round it out. Everything else can be grabbed from a hardware store. The plunger is a sink plunger on a piece of plastic lawn sprinkler pipe, spraypainted black. The eye i got a lamp cord with bulb socket (pic in link)
and ran that through some ABS plastic drainpipe and coupler.
The raygun is a paint roller spraypainted silver, inserted into a tissue box.
to secure all the parts that hang off and away from the tree, I ran fishing line to the ceiling. so the raygun, plunger and eye all have fishing line supporting it otherwise it would all fall off the tree.
the silver panel parts in the tree are wide christmas ribbon held on with clips.
the lights are just run in up-down fashion along the bottom third of the tree. I had little star ears on mine, but they were pretty unnoticeable.
Any other questions in particular just ask - good luck and happy christmas
