Question : Make seperate words appear in powerpoint 2007

Head's spinning now, is it possible to make single words appear.
Yes, I know you can do it for text boxes, but I would like a word in the middle of a sentence to  appear. This would happen for a number of words in a paragraph; each one to appear at different times according to mouse clicks etc.
I've tried creating multiple tect boxes, one for each word; my brain's just exploded!
Any ideas
Cheers
John

If you want to insert a new word into the text, you can use code like this instead of line 9

tf.TextRange.Text = tf.TextRange.Words(1, 2).Text & "newword " & tf.TextRange.Words(3, 2).Text

This will plug a new word between the second and third word of a four-word sentence.
