On the hose put a mark with the marker every 5". In between the 2 marks you have 1L of water.
If you promise to be very careful a grown up might lend you a barometer. It will allow you to understand better how weather works. If the weather is nice then you are in a high pression system and if it’s not then you are in a low pression system (most of the time)
