How to attach acoustic foam?

[Zoofie]

Hey guyss
I recently got hold of acoustic foam for my studio , and am looking for a way to attach the acoustic tiles to the wall. I want to attach them with something that if i have to take them down , it want rip the plaster off the walls. I have tried blu-tac but its not strong enough.
I have heard some people attach them to a separate panel but that won't work for me because i need them in a specific shape.
Any ideas?
Cheers!

Maybe 3" or 4" long will do the trick.

Thanks! Are they strong enough to stick into the wall then? Thanks again!

It's a tack essentially with a longer stem and different head. So yes.
