Sea Rockets: Incredible Sibling Plants

Sea Rockets are incredible sibling plants. They can tell whether the plant next to them was sprouted from an unrelated seed or from the same mother tree.

When they sense that the foliage next to them belongs to a sister plant by using chemical signals, they don't compete with the others. But when they are in a place alone with other species, the Sea Rocket sends out more and more roots so it can become more established than its competitors.

There is a theory that plants can see, think and have some kind of communication, and this is proof. It seems that plants should be able to know what they're doing if they are able to droop when touched (The Shy Plant) or dance in the windowsill (Dancing Grass).



The Colossal Explosion: Yellowstone's Massive Volcano

       When Wyoming was still a territory, Lieutenant Gustavus Doane, head of an exploring expedition, noticed something strange when looking out from the top of a mountain. He noticed that there was a giant volcano. But the Lieutenant, even though he made a good guess, thought wrong: in his mind, the ancient crater was extinct.

    ldfthflgysr.jpgTwenty craters have been in existence since mighty sheets of ice covered Yellowstone National Park. The volcano is known to be the cause of all the geysers, mud pots, terraces, and hot springs in the park.

When we went to Yellowstone, we liked seeing the mud pots (even though they smelled like rotten eggs) and we saw Old Faithful erupt three times. Then we went to Morning Glory Pool (a multicolored hot springs.) But, while we were there, we didn't see any symptoms that the supervolcano's blast was going to happen soon.

    Earthquakes have been happening recently (which is a sign that the park could explode soon). However, scientists say the eruption could happen anytime from next week to the next millennium. The future is anybody's guess!
