Ask Liz: Christmas Trees, Highway Speeds & Coffee Cream
In case you missed it on-air...
How can you prevent your Christmas tree from becoming a fire hazard in your home? We checked with the National Christmas Tree Association:
- Keep your tree hydrated. Once you get home, place the tree in water as soon as possible -- no later than 8 hours after the trunk is cut.
- As a general rule, there should be one quart of water per inch of stem diameter in your Christmas tree stand.
- Check the water level often. Some trees may take in a lot of water, especially within the first few days.
- Keep your tree away from sources of heat such as fireplaces, heat vents, and direct sunlight.
- Turn off the tree lights when leaving the house or going to bed.
A viewer says he sees signs on the highways that say, "speed enforced by aircraft". How does this work? The Insurance Institute for Highway Safety says:
- Officers in aircrafts can measure vehicle speeds based on the time it takes for your car to travel between pavement markings on the road.
- When a trooper in an aircraft picks out a traffic offender, he determines the car’s speed and then radios that information to an officer on the ground.
- That officer can then pull you over and write you a citation for speeding.
Why don’t individual packs of coffee cream need to be refrigerated? Coffee cream manufacturer Coffee-mate had this answer:
- Individual packs of coffee cream don’t need to be refrigerated because they are packaged at a high heat.
- When products like coffee cream are packaged in this way, they are said to be "shelf stable" which means that you don’t have to refrigerate them.
- However, once the container is opened and exposed to air, you will need to refrigerate it.
