The greatest invention ever

That would have to be plastic bins. Yes, the plastic bins you can pick up at any local store. The plastic bins that come in numerous shapes and sizes and colors. Not only do I love them because I have a fetish for organizing (which I need to say I am not so good at but I love the attempt). Not because some of them come with lids that you need the strength of a superhero to remove, thus making it almost impossible for a certain child of mine to open and dump the entire contents all over the house without my knowledge. But because I have discovered a new way to use them. I call it bucket head aliens.
Yup, just place that plastic bin on top of your childs head, wrap a long blanket around their shoulders and let them wonder throught the house talking and making loud alien sounds at the top of their voice. Its okay, because you'll barely hear those muffled voices. So play on, my little bucket head aliens...
