This is a way to use any type of plastic stuff: bottle lids, shampoo lids, prescription bottles, aerosol lids, any type of plastic. You take a cookie sheet and line it with foil. Turn your oven on to 450-500 dergees F. You line up the plastic you want to melt. Put some on their sides or stack a larger one on a smaller one. Put in the oven.
Keep a close eye on them. When they start to melt, they get in different shapes. Don't let them melt to just a flat blob. While the plastic is still hot and semi-molten, you can embed different things in the plastic (small toys, buttons, beads, odd metal pieces) or you can put pieces of crayon or glitter in them.
I keep a baby wipe box marked "Pirate Treasure" filled with these things. Kids love to look through them or hide and find them. Once my nephew was visiting and I had him melt an orange lid with a smaller one of blue kind off to the side. While it was hot, he stuck a plastic dinasaur in the orange. It made a small diaorama. He put metal loop off the side. This made a neat keyring. When it was cool, I added some glitter nail polish on the blue so it looked like waves. I wish I had a picture of it. It looked like the dinasaur was on a beach by the water.
Sometimes if the item won't stay in the melted plastic, you can use a spoon to bring the plastic up over the item to hold it in. Of course this is done with adult supervision. The hot things can be placed in water to cool faster. While I used a regular over, a toaster oven might work better.

Editor's Note: Be sure that you use proper ventilation when melting plastic as it may create harmful fumes.
