I didn't want anything liquid - I have some really rough and tumble boys this year - I was not going to take any chances of slick floors - so mine just have treasures to seek inside much like my Christmas I Spy Jars.
We didn't have the candy cane tubes here so I used these:
There are mini ornaments inside.
They once held horrible jelly beans - so no great loss to dump them. :)
The red bead like filler is plastic melts for stain glass creative.
The kids are having fun shaking them as well - the sound they make is like a maraca. So they are not just a visual sensory toy but a sound toy as well.
