sand timers

Sand Timers  

In my story we made sand timers.It tells you what time it is.

We made them with bottles and sand and cardboard.

And you need to cut the tops off the bottles.  Make a hole in the lids and tape the two lids together.

I found that my sand timer didn’t work the first time because there were heaps of holes at the bottom, and we had to add more hot glue.  The hole in the lid was blocked and we had to opened the whole more.
