The Blue Milk
5 minutes · Low cost · 2–10 years · No mess

The elf was busy at the fridge last night. It was attempting a potion to make the house brighter through the dark weeks, and the potion went straight into the milk. The whole carton now glows a brilliant blue. It is only food dye, but the faces at the breakfast table are worth every drop. Two minutes of work, and the children talk about it for a week.
What you need
- Milk, dairy or not (1 carton)
- Blue food dye (a few drops)
How to do it
- Take a nearly full carton of milk out of the fridge.
- Open it carefully and add 3 or 4 drops of blue food dye.
- Close it and shake until the shade is even all the way through.
- Put it back in the fridge and leave a tiny elf tool beside it — a doll's spoon or a small glass vial.
What you tell the children
“Careful, this milk is magic! Whoever is brave enough should taste it and report back whether blue tastes of anything at all. (Spoiler: it does not.)”
The note the elf leaves
It was so dark in the kitchen that I tried to bring in a little moonlight. It seems my spell went into the milk instead. Oh dear.
