We are planning a stream table with sand for a traveling exhibition (for children ages 3 to 8) and would like to know other people's experiences with design, maintenance, and safety. How has sand worked? Are there other materials to use instead of sand that work better (e.g. pea gravel, plastic pellets)?
Thanks for any feedback you can offer!
