Ice At the Bottom Of The Glass
Have you ever got a drink on a hot day filled with lots of ice to keep it cool. But when you try and drink it the ice gets in the way of drinking it as quick as you want to. My idea is to put the ice in the glass first and add a plastic filter into the glass to trap the ice at the bottom and then pour the drink in. This is really simple but it would hold the ice at the bottom of the glass keeping the drink cool, and it would not get in the way of you drinking it.
