Frog Rush

You are a brilliant researcher who toils away in a top-secret facility. It was not your fault that the spill occurred, which then caused the nearby lake to become tainted with toxic chemicals and turned all of the frogs into dangerous amphibians. Okay, it could have been, but we all have our bad days sometimes. However, at this point, you are required to find a solution to the problem and ELIMINATE ALL FROGS. You can accomplish this by providing the frogs with a steady supply of the valuable "Chemical K." The frogs appear to enjoy this and will continue to grow larger with each drop until they are fully primed, at which point they will explode, spraying potentially lethal frog blood everywhere. Because any frog that is hit will also explode if it has been primed, you need to make sure that the perfect chain reaction occurs by utilising the meagre supply of Chemical K that you have.
