DEAR HELOISE: I am not sure if you’ve had this idea suggested before. Air duster cans (compressed air in a can) is great for cleaning computer keyboards and other devices. However, I also use it to blow out small hairs in the beard trimmer and when getting into hard-to-reach areas while I’m working on projects, such as woodworking. There are 101 things you can use it for in lieu of a big bulky electrical compressor.

DEAR HELOISE: For ladies and gents, if you find yourself at a business or party event, here are some hints to keep you safe:

• Don’t accept a drink from anyone if you didn’t see it prepared.

• Don’t leave your drink or bag unattended.

• When entering a meeting room, know where the exits are.

• Don’t drink and drive or accept a ride from anyone who has been drinking.

DEAR HELOISE: Why does the doctor’s office staff tell a patient that her appointment is at 10 a.m., then say, “Come in at 9:30 a.m. to do paperwork”? Either the appointment is at 10 a.m., or it is at 9:30 a.m. Or perhaps there are two appointments, one with staff and one with the doctor. I find this bait-and-switch procedure to be rude.

If there is a need for paperwork to be done, this should be a part of the appointment time.

DEAR HELOISE: I’m a man who cooks for the whole family. How do you make the real fluffy scrambled eggs like they do in restaurants? I have tried adding milk and water, but no luck. Can you help?

— Denny Z., in Wellsville, Pennsylvania

Denny, here is the method I have used for years to achieve fluffy scrambled eggs:

First, make certain that you whisk the eggs vigorously until they’re light and airy. Then add butter to the bottom of the pan and be sure that the pan is hot before you pour the eggs into it. Using a heat-resistant spatula, gently push the edges to the middle of the pan and keep doing this until there is no liquid left.

A few seconds before the eggs are done, remove them from the heat because the eggs continue to cook. This is how we do them here at Heloise Central.

DEAR HELOISE: How can I avoid onion tears?

— Della K., in Austin, Texas

Della, put your onions in the freezer 15 minutes before using them or in the refrigerator overnight. Either way, it will reduce the spray of onion oils.
