Right after leaving the platform, the only significant force acting on the bungy jumper is his weight. This causes him to speed up from rest. His speed increases every second by nearly 10 m/s. This is not the maximum acceleration experienced by a bungy jumper, however.

Answer video: https://www.youtube.com/watch?v=BickMFHAZR0
The longest vertical straw you can use is 10.3 m http://www.youtube.com/watch?v=HUmZrtiXDik
This is because the weight of water in the straw must be supported by the pressure difference at its two ends. At the bottom, the pressure is atmospheric, and at the top, the lowest pressure you can create is a perfect vacuum (pressure = 0). Atmospheric pressure can support a water column about 10m high - BUT with 0 pressure at the top, the water would start boiling. This is called cavitation and it obviously can't be happening in trees.
After I posted the straw video, I received a lot of questions about how trees could be taler than 10m. I assumed there was a simple answer because there are plenty of trees taller than that. But as I asked around and read articles about it, I couldn't really find an explanation I was happy with.

Maybe there is not a continuous water column inside the tree, so each section only lifts water a little ways? This could be but it seems to require a series of pump mechanisms, and how would you join this pump sections together? Perhaps capillary action is holding the water up? But the xylem tubes in a tree seem too wide (~50 um) for this effect to be significant. Maybe osmotic pressure could push the water from below rather than sucking it up from above? But some trees live in mangroves, where there is much higher solute concentration in the sea water than in their roots, so osmosis would work the other way.

Eventually I spoke to a plant biologist and sorted this all out, but I wanted to give you a little back to school challenge. How do you think this could work?

Estimates say that a vehicle-sized asteroid explodes in our atmosphere about once per year, often too high to make a noticeable impact.

But in 2013, a small meteor exploded just 20 miles above Chelyabinsk, Russia that sent over 1,200 people to the hospital.

Today, a team of experts from NASA’s Planetary Defense Coordination Office works diligently to find asteroids that travel near Earth’s orbit.

They’ve released a plan in order to prevent a large-scale asteroid impact, and part of this plan is the DART mission.

DART aims to travel to the asteroid Didymos in 2021 to demonstrate the tech that could be used to redirect an asteroid headed for Earth.

Earwigs are equipped with some pretty imposing pincers on their rear, and they're not afraid to use them. But when it comes to these appendages, size isn't everything.

DEEP LOOK is a ultra-HD (4K) short video series created by KQED San Francisco and presented by PBS Digital Studios. See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small.

Many animals seem to show a preference for symmetry in a potential mate. It can be a clue that the mate has the genes necessary to develop properly and thrive in an environment full of stresses and dangers.

But in some critters buck the trend. Like the earwig, a diminutive insect found on every continent except Antarctica.

Andrew ZInk, an associate professor of biology at San Francisco State University, has been looking at how symmetry affects earwigs success when it comes to social interactions.

He’s studying maritime earwigs, a larger and more powerful cousin to the common European earwig you might find in your backyard. Both creatures bear fearsome looking pincers on their backsides. And they aren’t afraid to use them to defend themselves. Zink knows all about that.

--- Do earwigs climb into your ear?
The quick answer is no. Earwigs are not interested in climbing into your ear to lay their eggs or otherwise. They’re no more likely than any other bug to accidentally find its way into you ear. The name earwig come from the old english words for ear and insect. It may have been named after the shape of the common European earwig’s wings, which when extended resemble a human ear.

--- Do earwigs pinch people?
Earwigs will use their pincers to defend themselves, but the pinch is typically not strong enough to be considered dangerous.

--- Do earwigs fly?
Male common European earwigs have wings and can fly to disperse and find mates. Females do not have wings or fly. Neither male nor female maritime earwigs have wings or fly.

--- What do earwigs eat?
Most earwigs are scavengers and omnivores. In addition to scavenging and eating plants, the common European earwigs also hunts small prey like aphids. Maritime earwigs are carnivorous hunting smaller arthropods like sand hoppers.
