It’s a hot day in Greendale and Ted Glenn has invented a special ice cream machine. He’s promised all the children ice cream for a picnic in the afternoon but following a power cut, has no means of operating the machine. Pat and PC Selby try to help but Pat’s van brings too much power and send ice cream flying whilst PC Selby’s pedal power results in an ice cream flood. Pat has the idea of using solar panels and harnessing energy from the sun. This works perfectly. The children have been busy finding different ingredients and Ted is able to supply the whole village with a wonderful assortment of ice creams – including sardine flavour for Jess.
