1. Water-saving shower head
Each time you start to run a shower, you have to stand around waiting for the water to heat up. But this shower head promises to end that delay.
You turn on the water, and it runs until the cold water runs out. Once the water temperature reaches 95 degrees Fahrenheit, the water slows to a trickle. Then, the water waits until you pull the cord.
You can do other tasks — such as shaving or brushing your teeth — and step into the shower when ready, knowing the water will be warm.
