My mom was good at playing silly food tricks - harmless as they are, still some are quite disgusting!
An eye opening morning - mom would often trick us with green food die in the milk, serve vinegar for apple juice, put string in the pudding, substitute mayonnaise for yogurt, put salt in the sugar bowl... it's definitely puts you in the mood for April Fools Day
Mom, ya gotta love her

A total time-waster but harmless. Take a bunch of paper cups and fill them about half-full of water. Put these cups on someone's desk, like about 20+ or more..

Methylene blue is harmless but passes thru the ole' body system leaving its color behind. Add a couple of drops into a dark beverage like coffee, coca cola, tea...whatever. The next time this person has to use the bathroom, they will have quite the surprise -- blue urine!
Open up a walnut along its seem being very careful to not break it. Then put odd items inside, like peas, sunflower seeds, rocks, whatever else you can fit in and then close back up using a touch of super glue so it seals well and is unnoticed. When your victim opens the walnut , they will be surprised and will wonder how a gummy worm or dried peas got inside.
