Last Minute Extracurricular Boost?

<p>I am a junior right now in high school, just wondering if there is anything I can do to boost my extracurricular activities between now and when i apply to college. I will be pretty busy during the summer with research and whatnot, but is there anything online (<-- haha) or any programs I can attend which could be recognized by colleges? </p>

<p>I live in New York/Long Island, if that helps</p>

<p>I believe research during your summer is your extracurricular.</p>
