Anyone who owns a paddling pool will tell you heating up the water is not easy.
If you've not got access to a hot tap from the garden, it can be quite a mission to get it to a nice temperature with numerous kettle runs.
And even with this lovely weather we're currently enjoying, taking a dip in the pool isn't enjoyable when the water is freezing cold.
However help is at hand, as mums have been sharing their ultimate hack for heating up chilly paddling pools with nothing more than bin liners, reports Manchester Evening News.
The hack is going viral in the parenting world - and it involves simply covering the pool in black bin liners.
One mum shared the tip and said: "I did this because I only have a cold outside tap and I was using buckets and the kettle to warm up the pool.
"By putting black bin bags on top it attracts the sun and it warms it up very quickly. Within about 45 minutes the water is warm and stays warm all day in the sun."
She's not the only one raving about it.
The idea was first shared on the Mrs Hinch Made Me Do It Facebook group after a woman asked for advice on heating her freezing paddling pool.
One person advised: "Fill with cold from outside tap then cover with black bin bags. Leave for an hour.
"The sun is drawn to the black bags and heats it up. Works a treat every time."
Well, we're off to try it for ourselves. Now where are those bin bags?
