Vilnus, Lithuania-based artist Tadas Cerniauskas who uses the name Tadao Cern has been experimenting with balloons for some time.

Vilnus，以立陶宛为基础的艺术家TadasCerniauskas，他使用了TadaoCERN的名字，一直在实验气球。

His concept and idea, Black Balloons, is based on experimentation with various gasses, suphur hexafluoride, carbon dioxide and helium, to control the weight of the balloons and, through that, manupulate where the balloons stay within a place without any tethers.

他的概念和想法，黑色气球，是基于各种气体，六氟化硫，二氧化碳和氦的实验，以控制气球的重量，并通过它，管理气球停留在一个地方，没有任何绳。

We love the concept for several reasons. We’ve been fascinated by balloon art for a while but these black balloons carry a different kind of weight, both literally and conceptually.

我们爱这个概念有几个原因。我们对气球艺术感兴趣了一段时间，但是这些黑色气球在字面上和概念上都有不同的重量。

The round shape is a familiar often connected with happy and positive ideas: the earth, moon, sun and many other celestial bodies, berries, fruit, the pupils of eyes, and of e, pubbles, balloons and pebbles.

圆的形状是一种熟悉的，经常与快乐和积极的想法联系在一起：地球，月亮，太阳和许多其他天体，浆果，水果，眼睛的瞳孔，以及e，酒吧，气球和卵石。

But when represented in black, even the happy balloon takes on a weight wnd starts to look slightly menacing and dangerous. We think of cannon balls and bullets, heavy rocks and Indiana Jones.

但是当黑色的时候，即使快乐的气球花在重量上，也开始看起来有点吓人和危险。我们认为炮弹和子弹，重岩石和印第安纳琼斯。
