While it is great fun balancing rocks, you could also have great fun balancing items in your kitchen. Everything from bottles, forks, plates, cookware, pots and pans. I personally balance items in my drip tray after washing them just so I can stack more items in there. Its not artistically done, but it gets the job done.
But for those of you who are more serious about doing such things, like the type of person who is so serious about their kitchen that they take private cooking lessons with a professional chef, then absolutely, go ahead and balance your cookware, baking tins, spoons, wine glasses and soup ladles.
Just don't forget to take a photo when you do something really amazing.
If balancing items in your kitchen isn't enough to keep you busy. How about learning to cook in your kitchen? Get Italian cooking lessons in Toronto in the privacy of your kitchen. It doesn't have to be Italian either, just pick a topic and get cooking lessons in Toronto with a theme of your choice.
