Experiment:
1. Form groups of five and give each group member a number, 1 through 5.
2. To ensure the experiment is blind, set up a testing sheet (example on last page,
which can be cut to separate participant samples), one for each person, with the
strips laid out in this order:
3. Start with round 1, having every participant put their strip on their tongue for five
seconds. Only part of the strip needs to come into contact with their tongue in
order for the test to work.
4. Have each participant record the taste of the strip on the testing sheet, in the box
they got the strip from.
5. Apply their results to the chart in the “background” section to classify them as a
taster.
