You make up your sugar syrup as usual, then pour it into gallon size ziplock bags. The real good quality ones. Fill only about 1/3 to 1/2 full and place directly onto the top bars as in the photos on Linda's blog. You make about 2-3 small slits directly in the top of the ziplock baggie so the bees can suck the syrup from the baggie.
Now you need to have an extra super to place on top to give the baggie room. Or I bought these special little supers (they are about 2 inches high) that you place on top to give the extra room. This is good for emergency feeding. The nice warm baggie sits right there onto the top bars. No bees drowning, no robbing.
