When leasing a car, some dealers will try to put you into a balloon loan which seems like a lease but it isn't. A balloon loan is basically a conventional auto loan with lower monthly payments and a large balloon payment at the very end. This balloon payment is usually optional - which means you can return the vehicle instead of buying it - similar to a lease.
When you boiled ionized alkaline water until it reaches the boiling point, the water molecules nearer to heat source will expand greatly until it transform into vapor gas, that is why you can see bubbles rising from the bottom.
Deionized Water (We call it DI water in the chemistry labs) is just what it sounds like: Water that has the ions removed. Tap water is usually full of ions from the soil (Na+, Ca2+), from the pipes (Fe2+, Cu2+), and other sources. Water is usually deionized by using an ion exchange process. Why de-ionize water? Often, when you are doing chemistry experiments, the ions in water will be an interference.
