Greeting card showing the Christmas formula for the absolute size of our stomachs, because we all get a bit piggy. Single cards or packs available.
Our stomachs are generally pushed to their limits at Christmas so this formula shows the absolute size based on our food consumption at Christmas.
The formula says... The absolute size of stomach is roughly equal to three turkeys, plus gravy over root veg, sum drinks, plus infinite chocolates.
The formula is explained on the reverse of the card.
Our range of Christmas cards come as singles or in packs of three or five identical cards.
We have more science-themed Christmas greeting cards available in the Newton and the Apple shop.
