A US man from near Kansas City gathered wild violets that were growing in his garden and demonstrated how the pigment can be changed by altering the pH once boiled down.<br /><br />Captured on April 13, this bitesize experiment demonstrated by Cameron Peebles shows how, after boiling down violet flower leaves, the pigment can be altered using lemon juice and baking soda.<br /><br />By adjusting the pH of the solution the blue pigment changes to pink or green.<br /><br />Peebles explained: "My lawn has hundreds of wild violets; I harvested the flowers, steeped in boiling water, and then manipulated the blueish color of the tea by adding lemon juice - an acid - to get the color pink and baking soda - a base - for the color green. <br /><br />"Not only is wild violet tea beneficial to one's health, but it also makes a fun & beautiful at-home science experiment!"
