Mrs. Halfpenny utilised her husband Harold while unveiling her latest scientific discovery.
The 56 year old amateur scientific boffin pointed out to the local paper the differences between her husbands balls in winter compared to when he was running about on the beach wearing a pair of swimming trunks in the June - August period.
She then passed them around to the attending dignitaries to inspect them carefully for themselves and told them to note the saggyness.
"My Harold must give up all sports during Winter time due to the significant decrease in the atmospheric pressure contained within the walls of his beloved beach balls", she stated eloquently, despite her false teeth slipping out once or twice.
Next up for the intrepid scientist is to show how her husbands avian pets change size during the year.
"I intend to study the shrinkage in my Harold's cock", said she, "there is a massive difference compared to when I married him"
