Rattle from Ceramic art pieces

Could you put blue tack or other similar material at the contact points to the wall. I'm assuming that is the rattle--but in any case, where ever the contact points are that are creating the rattle, if you can put something like that--they make similar products in white as well.

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.

Blue tack is better than the no name blue poster gum that David99 mentions. The no name is MUCH more sticky and gummy, and tougher to remove. Also, any chance of placing a towel or wash-cloth over the ceramics while you are listening?

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.
