Rattle from Ceramic art pieces

Nail them to the wall.
Seriously,Poster gum or whatever its called is similar to blue tack and cost <$1 at wal-mart.
only need a little ball at the contact points.
May leave residue but that comes off with a little alcohol.

I have purchased 'no name' (Cant remember the name) that wasnt sticky or gummy.
If you want to spend $10 + S/H for the almighty BLUE TACK then go for it.
Other stuff works as well.I made the dumb mistake of buying 'the audiophile' stuff and passed it around to friends.Its gone now but the cheapo stuff is just as good,actually better if you consider the outrageous price of BLUE TACK.

Fatparrot-I live in N.Y. Nothing gets sticky or tacky here. :~)
I do not remember the brand name of the stuff I had a while back.All I remember is it was blue and came from wal-mart.
I feel it was exactly like blue tack.
I dont have it anymore as my daughter got a hold of it and used it up on her posters.
Next time I hit that store I'll see if they still sell this particular brand and let ya know.
