Systemic weed-killer, like those made with glyphosate, should be applied directly to the weed you want to get rid of. Do not apply these products to your entire lawn. Glyphosate products kill all vegetation and should only be applied directly to the leaves of the dandelion.
That's one giant leap! Alan Eustace, a senior vice president at Google, set a new world record today by completing the highest-altitude skydive yet--parachuting from 135,908 feet (or 25 miles) above Earth. The record was previously held by daredevil skydiver Felix Baumgartner, who leaped from 24 miles above Earth in October 2012.
Traveling at speeds of up to 240 mph, 164 skydivers flying head-down built the largest-ever vertical skydiving formation on Friday over central Illinois, smashing the previous record. It took the international team 13 attempts to beat the 2012 mark set by 138 skydivers.
