Mega sand timer, an educational tool in the classroom and kindergarten, is a large sand timer for kids. It’s huge, so kids can see the sand flowing down pretty clearly.
The material of the caps is ABS, while the tube is acrylic. They protect the glass bulbs inside from broken. So it’s safe for kids. To the tools for kids, safety is always the first thing to consider.
I bring a 15-minute timer home for my 3-year old daughter, she likes to see the sand flowing down, and sometimes she put her teddy bear on the timer and said, you are here, I would be back later.
