I'm planning on drilling into my wall and putting screws into hang a floating shelf I got from Ikea. It's fairly small (about 30cm x 30cm) but I would like to leave about 10 text books on it. http://www.ikea.com/aa/en/assembly_instructions/lack-wall-shelf__AA-200208-9_pub.pdf
The problem is that I'm in an apartment and the wall is platerboard/ gyprock. How can I safely drill into it, or alternatively what would be a strong stick on hook that I can use?
