The colour and weight of the cutlery you use affects the way your food tastes.
This could be used to help people trying to lose weight or restaurateurs attempting to make their meals more appealing (via lightweight utensils in shades that match the food itself).
Today’s invention is therefore cutlery each item of which is a hollow transparent shell with a secure stopper.
These can be filled, prior to serving a dish, with a fluid which varies in density (think syrup or water vs whipped cream) as well as colour (using food dye -or even elements of the meal itself).
After use, the utensils can be opened, cleaned and reused.
