I just iced a bug and it was like it was made of water

I grabbed a water bottle from the fridge to throw at it. I threw it gently. The bug had froze solid and bounced off the wall like a drop of water. It shattered into a few peices. I have never thrown ice at a bug before. <br>Can someone give me the answers to the following:<br><br>1. What did I just hit this bug with<br>2. What happened to the bug when I hit it<br>3. How does this make you feel<br><br>As a bonus, what bugs are made of water?<br><br>Thank you
