Redmi Note 7 climbs up to the stratosphere in a balloon. Here’s what happened

In an attempt to prove how durable their smartphone is, Redmi by Xiaomi launched the Redmi Note 7 in space. The smartphone was nestled in a custom built case on to a gas balloon. According to the video released by Xiaomi, the custom rig rose as high as 35 km into the atmosphere with a temperature of -60 degree C. After the balloon exploded, the smartphone made its descent back to the surface of the earth.

According to GizChina, the 3D printed frame was designed to protect the handsets at that high altitude. The smartphone was found to be unscathed after its touchdown.

Redmi has previously tried proving the durability of the smartphone in several video commercials. In one of the videos posted on the Chinese social media platform Weibo, a person was shown hammering a nail in a block of wood using the smartphone’s display. Unsurprisingly, the smartphone survived the abuse.
