Fluid dynamics researchers Jacy C. Bird and William D. Ristenpart were doing routine experiments on water droplets, when the supposedly predictable outcome failed to materialize. Instead of coalescing as expected, the charged water drops they were testing began repelling each other—a result that seemed to fly in the face of elementary science...
...Bird said the findings suggest this process will only work up to a certain voltage...
...What’s new is that above a critical electric field, the water drops show a direct contact and repel—against what is believed [will happen],” said Bird, a Harvard doctoral student in engineering. Instead of infinitely increasing the coalescing speed of water, an electric field above the critical level causes the drops to deform, combine briefly, and then repel, never actually coalescing...
...blockade drove most of Gaza's economy, including parts of Draimli's pet business, underground. "Now we bring things like bird cages through the [smuggling] tunnels [on Gaza's border with Egypt]," he says, adding that they are no longer allowed to import the cages from Israel. "The price in Egypt is cheaper than it is in Israel. But the problem is that we have to pay $50 for each container to bring them through the tunnel. So we can't make any money...
...even after the war, he says, some Gazans have continued to find a need for his luxury goods. "The desire to have pets grew in Gaza after the Israeli invasion, because the children were constantly afraid," he says. "So every family that could came to buy a cat or bird for their children to comfort them...
