This is What's Trending Today.
A teenager from the northeast state of New Hampshire has one of the top trending YouTube videos this week.
Lily Hevesh is known as Hevesh5 on YouTube. She is an expert at making domino art.
Dominoes are plastic rectangles used in a game that is popular around the world. The rectangles are white with black dots or black with white dots. They are called tiles.
Players must play one tile at a time, matching one of their tiles with another tile already played.
But there is something else you can do with dominoes. You can place the dominoes upright and knock them down.
One domino falls and knocks down the next domino. The lined-up dominoes create a chain reaction. This is where the expression "domino effect" comes from.
Hevesh is a master at making complex and creative domino art projects. She uses multi-colored dominoes. When they fall down, the design changes color.
Her work has been featured in a car commercial and a popular morning television program.
On Saturday, she released a video of her latest domino project. It is called "The Amazing Triple Spiral." She made the design using 15,000 dominoes.
It took her 25 hours and eight days to complete the project, she said.
Hevesh laid the dominoes on the floor in a wide spiral pattern. The blocks are all different colors – orange, yellow, blue, red, white, and green. Some of the dominoes are stacked on top of each other.
When she knocks down the first domino, it starts the chain reaction. It lasts for about 90 seconds.
First, the dominoes on the inside part of the spiral fall. Then the dominoes climb a stairway. The dominoes standing higher up on a platform then fall. Then the platform itself falls. The platform was created by placing five layers of dominoes on top of each other.
Hevesh's latest design quickly impressed YouTube viewers. It has been viewed almost 3.5 million times.
One viewer wrote, "I couldn't imagine myself spending 25 hours to build that, even if I had the dominoes."
Another wrote, "Incredible, a whole new level and very artistic."
Hevesh once told her local newspaper that the best part about making domino art is "knocking them down and seeing it was successful."
But, not all of her projects turn out as well as her latest creation.
In August, Hevesh and another domino artist worked on a huge domino tower. The artists were trying to break the world record for the tallest domino tower.
They worked for seven hours putting more than 3,000 dominoes on top of each other. The tower was almost six meters tall.
Then, Hevesh accidentally knocked over the tower. Although they did not break the world record, they still broke the American record for tallest domino tower.
And that's What's Trending Today.

莉莉YouTube上人称Hevesh5 。是多米诺骨牌方面的专家 。
多米诺骨牌是长方形的塑料，是一项风靡全球的游戏 。这些长方形的牌，要么是带着黑点的白色牌，要么是带着白点的黑色牌 。这些牌也叫tile 。
多米诺骨牌还有别的玩法 。可以将所有牌摆放好，然后一一击倒 。
一张牌倒下，并撞击下一张牌 。连成排的多米诺骨牌形成了连锁反应 。这也是“多米诺骨牌”效应的来源 。
莉莉很擅长制造复杂新颖多米诺骨牌阵的小能手 。她用的多米诺骨牌颜色多样 。随着牌的倒下，牌阵的颜色也会发生变化 。
周六，莉莉发布了她最新的多米诺骨牌阵视频 。名为“神奇的三重螺旋” 。其中，她用1.5万张多米诺骨牌制作了牌阵 。
她将牌在地面上摆成一个大的螺旋形状 。颜色各异——有橘色、黄色、蓝色、红色、白色、绿色 。其中一些牌摞在其他牌上 。
当它放倒第一张牌时，连锁反应就开始了 。总共持续了90秒钟 。
首先是螺旋里侧的牌开始倒下 。然后呈阶梯式向上的放下一一倒下 。然后是更高平台处的牌纷纷倒下 。然后整个平台也开始倒下 。平台是由五层多米诺骨牌分别罗列在彼此之上组建而成的 。
莉莉这项最新的设计迅速吸引了YouTube上的大批网友 。视频浏览次数达到近350万次 。
8月份的时候，莉莉和另一位多米诺骨牌专家合力组建了一个大型多米诺骨牌塔 。他们当时的目标是打破最高多米诺骨牌塔的世界纪录 。
他们历时7小时，将3000多张多米诺骨牌罗列起来 。塔身高达近6米 。
然后，莉莉不小心打翻了这座塔 。虽然他们最终没能打破世界纪录，但仍然打破了美国最高多米诺骨牌塔的纪录 。
