An Idaho man turned a sour taste into a sweet achievement last week when he drank a liter of lemon juice through a straw in under 17 seconds for a Guinness World Record. David Rush, who has broken more than 100 Guinness records to promote STEM education, emptied the glass containing a whole liter of 100 percent lemon juice in 16.53 seconds. Rush's time bested the previous record of 17.12 seconds, set by Andre Ortolf.
