Cool idea for your Canada Day (or in a few days Independence day celebration).
I found this on The Toy Zone and thought it was a pretty cool idea. I would have never thought of this, but I can't wait to try it now.
Here is what they said:
"These are an extremely funky way to add fun to a party. However, if you haven’t got any friends you can add them to your glass of whiskey and revel in your retro funk.
To make these all you need is some old LEGO bricks and a slab of modeling clay. Insert each LEGO piece into the clay and remove – bake, fill with water and freeze."
