  1. Yes peleas climb a building

  2. Awesome video!

  3. I was taught in class that Van de waal forces were basically negligible, but clearly it isn’t.

  4. Just imagine if the rich paid taxes and we funded science and education.

  5. Wow! Thank you for your great work

  6. Geckos! one of God’s amazing creations!

  7. i finally understand how geckos stick. thank youi

  8. 10:10 WTF is “prawduce”? Guess you don’t need American English to get into NASA.

  9. I find the lack of MI:4 references concerning. How could you not mention the movie? This is outrageous! (jk)

  10. My butt was clenching during the car pulling test. It didn’t feel safe that all of you were so close to it LOL
