Get up very early in the morning go and get the salt shaker and the sugar container. Put the sugar in the salt shaker and salt in the sugar container, put them back in the place they where in before. Run back to your bed and wake up when everybody else is up and offer to make breakfast make sure it's something that needs salt when you serve your food. Say "I just remembered that I need to put my homework in my school bag!" now run into the back yard and watch from the window. See how someone put sugar on there breakfast and salt in their tea, then wait for that first bite and then the sip.
