| Do how come plane propellers don't torque planes out of balance? Posted: 03 Aug 2017 08:11 PM PDT Helicopters need a tail propeller to counteract the torque that is applied from the blades. But old biplanes are an example of a planes that only have one propeller so shouldn't the plane be off balanced by the torque applied to the propeller only in the opposite direction?

| Posted: 03 Aug 2017 03:50 PM PDT Does fire spread, or does the heat from the previous flame match the autoignition temperature and make more flames? [link] [comments]  |
| Why do worms come out of the ground onto the footpath when it's raining? Posted: 03 Aug 2017 03:12 PM PDT Whenever it rains, the footpaths in my neighbourhood are covered with hundreds of worms. Why do they come out of the dirt to lay on these hard wet surfaces? [link] [comments]  |

| Posted: 03 Aug 2017 08:15 PM PDT I learned from chemistry class two years ago that water isn't a good conductor of electricity due to its inability to create ions. With that in mind, where is the danger (besides the ones obviously depicted on warnings) in water making contact with bathroom appliances? Do the metal parts and wiring pose a bigger threat, perhaps? (I'll delete this question if it's too rudimentary, but the thought of this popped into my head recently and I don't quite recall my chemistry too well) [link] [comments]  |

| What makes meth labs so dangerous? Posted: 03 Aug 2017 05:16 PM PDT It's widely known that meth labs are practically ticking time bombs, but what actually causes the explosion? [link] [comments]  |

| Is there any credibility to the Solutrean hypothesis? Posted: 03 Aug 2017 11:35 AM PDT A lot of people distort the hypothesis of humans crossing the Atlantic Ocean through an ice bridge from Eurasia into North America with their own, contemporary political or social biases. Putting that aside, is there any credible evidence that shows whether the Solutrean people could have come to North America and become the Clovis people, or has that hypothesis been discredited?

| Posted: 03 Aug 2017 09:14 PM PDT I'm assuming it has to do with the size and speed/terminal velocity of the object, but I'd like more detail [link] [comments]  |
| Posted: 03 Aug 2017 04:04 PM PDT I kind of understand how lakes formed in the northern hemisphere by glaciers, but what about other ways they can form, and I just do not know how ponds form in the first place. [link] [comments]  |
| What protects astronauts from the acoustic shock of a rocket launch? Posted: 03 Aug 2017 10:49 AM PDT From what I understand, the safe distance from a rocket launch is usually over a mile away. So what protects the astronauts from the harsh vibrations? [link] [comments]  |

| Posted: 03 Aug 2017 05:51 PM PDT I know that our moon rotates perfectly to where we can only see one side of it but I had never heard of a planet where the moon rotates fast enough to where you would have to trek across the planets surface to the other side in order to actually see it. Is it possible to have a planet/ moon interaction like this? [link] [comments]  |

| How did plants pollinate on early earth? Posted: 03 Aug 2017 04:15 AM PDT This is kind of a two parter. How did plants pollinate during the dinosaur era of bees weren't around? And earlier than that; how did the first plants on land get pollinated? [link] [comments]  |
