Just about every child does this. They don't understand well enough at 12 months to change much behavior. It's just so exciting to learn about physics, falling and watching you pick stuff up. My son did this for a while, then when he was about 2 he decided to break every breakable dish in the house. It wasn't a malicious act, he was interested in cause-and-effect. Each phase only lasts for a while and you wish you could have them back once they're gone. Good luck.
