Transparent Gas mask that only gets opaque when needed and can reduce in size for safe keeping

Many hongkongers say that they just want to protect their privacy or save themselves from air pollution. So we are doing IRD on emergency basis for a new gas mask that is transparent but can get opaque for some time by adding a liquid spray. This mask can also reduce size to as little as 1cm2 making it easy to keep in bag or socks or even backcover of your phone etc. As the IRD is urgent, we need money urgently to pay for moulds and testing. We expect to release in market in 10 days.
