On Fridays, we ask a bunch of unrelated questions. Your answers help get us through the afternoon. Answer one, answer all, or ask your own question. On to this week's topics...

1. In Jessanne's editor's letter in the current issue of mental_floss magazine, she shared this picture of her groundbreaking botany research from the mid-80s. What was your best/worst science fair project?

2. In the back of our cabinet, safely stored for the least special occasions, I have four Atlanta Hawks/Atlanta Thrashers plastic cups acquired at a 2003 Bruce Springsteen concert at Philips Arena. I'm not sure how they've lasted this long—I've moved three times since I first brought them home, which means I keep actively deciding to take them with me. What's the strangest souvenir cup hiding in your cupboard?

3. From 1987-1990, I probably watched Back to the Future 200 times. It was the first VHS tape I ever bought. This obsessive viewing was put to good use 18 years later, when I dumped all that knowledge into this Back to the Future quiz. What one movie have you seen more than any other?

4. Got a question for the group? Ask it here. Have a great weekend!
