Pep up Your Pastry Now you can one-hand that coffee-and-doughnut breakfast. Robert Bohannon of Environostics, an R&D firm in North Carolina, has concocted a caffeine-laced doughnut that packs a jolt equal to two cups of coffee. Normally, caffeine in baked goods imparts a bitter taste. Bohannon has concealed the drug in tiny, edible capsules that dissolve in your stomach, not in your mouth. Look for caffeinated snacks within six months.
