This grenade-shaped scent diffuser has been designed to alert internet users of data leaks from their smartphones, tablets and computers.

The Smell of Data fragrance bottle releases a metallic scent when a user encounters an unprotected website or Wi-Fi network on their devices.
Leanne Wijnsma and filmmaker Froukje Tanto created the product in response to concerns about data security on the internet. The project aims to educate users about what is going on with their data.
Wijnsma and Tanto evolved the concept by researching the human response to gas leaks.
"Compare the Smell of Data with the smell of gas," said Wijnsma. "We were taught to find this smell dangerous ? and we know exactly how to act when we smell it."
The designers were particularly inspired by a 1937 explosion in the US state of Texas that was caused by an unnoticed gas leak. The incident prompted the government to artificially add scent to odourless gases, making them more readily detectable.
Wijnsma and Tanto received an e-culture grant from the Dutch Cultural Media Fund to develop Smell of Data in 2014 and launched it in September 2016 at the Science Museum in London.
