1960s Ray Gun Made Of Space-Age Cardboard
By bohus
Before space patrol issues you a real ray pistol, they may have you practice your "pew pew" gun skills with this cardboard replica. It's got a deadly looking ("deadly" in that it looks like it might not be well insulated against all of that killer voltage") gun printed on both sides as well as a folded over hinge along the top.
The surprise comes if you hold the gun slightly open and bring it down quickly. A pocket of paper flaps out quickly with a loud crack. My gun is a little out of comission because it is quite old (clearly my weapon fell through some fissure in time connecting the 50th century and the 1960s), but an intact gun will issue a loud report.
While scarcely a replacement for a classic plastic or tinplate ray gun, but as a freebie with a business name printed on it... not too bad. Though labeling it "all mechanical" is a little optimistic.
Cool thing for you, dear reader, is that I found an eBay seller who has some new old stock for just a few bucks, so you can have the real thing that's intact enough to actually have fun with. You can also fold your own popper by following the link below. It won't look as cool as the paper ray gun, but it's loud enough to get you kicked out of a Junior High School lunchroom as I recall...
