It has animal hairs coated with ionic liquid gel to pollinate a flower like a bee. They may be small, but bees and other insects play a critical role in pollination and maintaining a natural balance in our environment.

Bumblebees and other pollinating insects help pollinate 75 percent of the fruits, nuts, and vegetables we eat and removing them from the equation could trigger a global food crisis according to the United States Department of Agriculture (USDA). The short term solution could lie with drones.
