Bomberman Bomb! Help needed

[Alrightman]

Hello! I want to make a classic round bomb prop, such as the one from Bomberman.

I have found a Styrofoam ball from a craft store. The problem is, I want it to be rigid. With what can I coat the styrofoam to give it strength, and do not end up melting it?

I wanted to use the old woodworkers technique of swiping superglue then activating it with the spray, but I know that CA glue melts styrofoam. I suppose fiberglass resin would too.

Any ideas?

What diameter do you need your bomb to be?

About five to six inches would suffice. The styrofoam ball I bought is around that diameter.

If you search Google for 6" plastic spheres, you're going to save yourself a lot of time trying to find a way to coat styrofoam with something that will stick to it without melting it. You could try milliput, but you are probably going to spend more time and money with that and still be stuck having to sand it smooth. A quick Google search found several plastic spheres that could do the trick. Another idea is to search second-hand stores for an old world globe or some kind of toy.

Go to your local plumbing supplies store, and see if they have a ball-float from a toilet cistern valve.
Not only will it be the right size, and rigid already with a far easier surface to paint... It will have a raised cylindrical section for your fuse as well!
