These are some hamster toys that my kids (with a little assistance from me) made for their friends and their pet hamster.
Next, using a hacksaw I supervised my daughter cutting a dowel that she would glue between the wheels.
The wheels were a little rough around the edges, so she had to sand them down first.
Then she could glue the dowel between the wheels and finish making the toy.
Once again I supervised my daughter as she used the hacksaw to cut some really thick tube that the hamster will crawl in to and chew on. This thick tube should take longer than just having a toilet paper tube.
She cut out 2 tubes and each child decorated one to give their friends.
