How can you take 9 toothpicks and make ten without breaking the toothpicks?
TEN (every line making the letters in the word ten is one toothpick. There are nine lines you draw when writing ten, so there are 9 toothpicks making TEN).
30 white horses upon a red hill,
first they start stamping,
then they stand still.
What are the 30 white horses?
