Why does ink and food coloring separate in blotting paper?
It has to do with the difference in affinity between the dyes that make up the ink or food coloring and the blotting paper compared to the solvent. This is paper chromatography. The dyes are carried along by the solvent (water) but is attracted to the substrate (the blotting paper). Some inks travel faster than others.

What is the color of the queens blotting paper?
I heard that The Queen uses black blotting paper in order that no one could read what she had written. I wrote to her to ascertain the veracity of this practice and received the following return from Miss Michele Edwards who is an Information Officer in Her Majesty's Press Office. Thank you for your letter of 22nd March. "The rumour about The Queen using black blotting paper seems to surface fairly regularly. There is no truth in this; Her Majesty uses ordinary bloting paper." ... more, not relevant. Yours sincerely etc.etc. I hope this answers you query.

How can I make my own battery to win a contest at school?
Use copper and silver coins, with blotting paper soaked in salt water. Stack the coins:- silver, blotting paper, copper, silver, blotting paper, copper, silver...etc. Attach wires to the lower silver coin and the copper upper coin. Stack the coins so there are at least four pieces of blotting paper soaked in brine. You can prove the battery's potential with a digital multimeter. It will not produce much useful current, but you should be able to get 3 volts out of it. You could get it to work a digital watch. (make sure you get the voltage right first.) You could also try sticking dissimilar metal plates into a lemon. Try copper and steel, but experiment with different metals, see which is best.
