But those watching coverage of the Olympics may have spotted the diving pools being watered between dives and wondered why this is done?
Here’s what you need to know.
Why do they spray water on Olympic diving pools?
If you’ve been watching any of the Olympic diving events, you may have noticed that water is sprayed over the surface of the pool between dives.
Although some may think the explanation for this is that it’s to replenish any water sloshed over the sides after a dive, it’s actually done as a safety measure.
The water spray create ripples across the water which then makes it easier for divers to see how far they are from the surface of the pool and they can therefore time their moves to end right before they enter the water.
Water being sprayed onto the pool helps the divers to see where the surface is, as with the diving board being 10m up, they can only see the floor of the pool from where they are standing.
The ripples created by the spray then allows the divers to judge the distance more accurately and make sure they enter the water at a safe angle.
As divers are travelling at around 35mph when they hit the surface, they can be seriously injured if they enter the water at a bad angle.
Other safety precautions for divers include minimum and maximum pool depths for optimum water pressure, as well as compressed air bubbles which are pumped from the pool floor to help soften the divers’ impact with the water.
What medals have the Team GB diving team won so far at the Tokyo 2020 olympics?
