Step 1: To empty them, open the cans from the bottom instead of using the pop tops. We want to preserve those. I use an old fashion can opener and try to keep it attached at the very end just a little. The newer can openers that cut the lids off on the outside are harder to glue back together. They don't quite fit back in.
Step 2: once your cans are empty, make sure you carefully clean them out and dry them. Just remember there will be sharp edges. Also, pull the label off at this point.
Step 3: fill the cans about half way with whatever candy you choose. I used hershey kisses and starbursts. Then to add some pretty, stuff a little tissue paper to fill the other half.
And then your done!! Your final products sure to wow your child's teacher! Total cost is around $1-2 a can depending on what kind of candy you use and whether you already have ribbon laying around. I already had most of the supplies in my craft drawers.
