This product might work for adults but not practical for children. The small microwave valve is very difficulty to put back in once pulled off by mistake. Also very difficulty to open. As an adult I can open goal it is a little challenging for me and not for my children. I suppose if They Have the Patience to try for a bit open goal They Can the food falls out When They are successful as They Have to struggle with it on icts side. Teachers Told me to stop sending to school UNLESS I want 'em to starve !!
