Night kayaking

We returned this weekend to where we went kayaking last weekend. This time is was in the evening to go kayaking for 2 hours at night. By going close to the shore which was blocked from city lights, you could see plankton in the water that was phosphorescent and would glow a little. By moving your hand around in the water, it would 'activate' the plankton more and would light up even more. We could even 'light up' the plankton deep in the water by moving our paddles around deep in the water. It was a very cool experience that unfortunately was too dark to take photos of...sorry.
