My list of Invisible Ink:
Cola drink (diluted)
Honey (diluted)
Lemon, apple or orange juice
Milk
Onion juice
Soap water
Sugar solution
Vinegar
Some inks are developed by heat.
You could use things that give out heat like a hair-drier or a heater. You could even use an oven without the flame. Just as long as it gives out heat.

My Prediction:
I predict that the writing will come out brown and you will be able to see it clearly.
What Happened:
We put it in the oven for about two and a half minutes and these were the results. The vinegar didn't appear, you can just see the tea, the sugar water and the coke, but the honey was seen clearly.
