My idea is to produce a special perfume.
The perfume will protect you against mosquitoes. But it will have an unusual scent, because it will smell like an expensive perfume but the smell will be toxic for mosquitoes.
It would be cool! Just imagine..You are having a date with your boyfriend. You are enjoying your date,.. enjoying a beautiful night... But your boyfriend suffers from mosquitoes and fans away them. It is funny, isn't it?
He doesn't have the unique perfume like you have.
