How to Attach Stuff to the Wall Without Drilling a Hole

I didn't want to ruin my kitchen tiles and wall by drilling a giant hole through it, but I did want to hang my knife and paper/foil thing to the wall. Solution: superglue and magnets.

*magnets (I got 250 rare earth magnets on Ebay quite cheap. diameter 0.5mm/0.25 inch but you might want slightly larger ones)
*superglue
*stuff to put on your wall.

I got this really beautiful kitchen knife from a friend. (we call it my Dexter knife because of its size ;) )
I already had a cheap knifeblock, but there was no spare slot for another knife, and I needed some place to put it.

Because the knife is quite heave, 1 magnet was not enough.
I grabbed 3x6 magnets, and superglued them to the wall.
Note that it says *dries within a few seconds* you should really be prepared to hold the lot for a few minutes. Make sure you dont get any glue on your fingers.

When the glue is dry, stick the knife to the magnets and make sure it holds ( as you can see, I touched the glue, and got some on the knife...)

The paper thingie was even heavier than the knife, so I glued 4 rows of 6 magnets to it.
When those are dry, put glue on the top magnets, and stick it to the wall - hold for ages until dry.
This way you do not have to measure out where to put the magnets on the wall, and you dont have to keep the polarity in mind either.

Edit.
Several people commented that my cat was scary..
Oh, come on ;) - My cat's not scary! Look - pure cuteness in this slightly better picture :)!

Confirmed Nov 2009: The glue/magnets can be removed with acetone (nail polish remover) and a dull knife (to scrape remains off tile) with absolutely no damage to the tile.
