Sand Timers (1, 3, 5, 10, 15, 30 minutes) 

A simple video of six different sand timers -
1 minute sand timer (white sand)
3 minute sand timer (blue sand)
5 minute sand timer (green sand)
10 minute sand timer (purple sand)
15 minute sand timer (orange sand)
30 minute sand timer / half hour glass (red sand)
Watch the sand fall and listen to the relaxing ambient music. It might help you fall asleep fast by watching the gentle motion of the falling sand grains, or why not just relax and watch the simple passage of time as an alternative to watching the seconds tick by on your watch or phone.
