An eyepiece is not necessary to see objects, but it helps to keep your eye off of the viewing lens. It can also make viewing more comfortable. Use a drill or sharp object (e.g. scissors) to make a hole in the bottom of a film canister. The hole should be in the center of the canister and large enough to slide the smallest tube through. Line the smallest tube up with the hole in the canister. Push the tube so that the top (side with the lens) inch is inside the film canister. If the tube will not fit, make the hole larger until it does. Use glue or liquid cement to keep the eyepiece in place. This will allow you to look through the eyepiece without it moving. Give the glue time to dry.

Summary: Make a hole in a film canister. Push the lens tube through the hole. Secure the eyepiece.


Even though they may be considered old-fashioned, a printed travel guide can be one of the best companions for your travel.  They will have suggestions for activities and ratings for specific companies.  The information in reputable guides is usually very accurate. Make sure you think of all of your travel companions when booking activities.  If you are traveling with children, be sure planned activities are kid-friendly.  If someone in your group has health or dietary considerations, try to be respectful of those as you plan the trip. If you want to do something special, like a tour of a special collection at a museum, a whale watching trip, a performance, a sunset cruise, or a very fancy dinner, make reservations ahead of time.  If you are going to a popular place during a busy season, special events may fill up, so you will want to be sure to book ahead. Be sure to find out about cancellation policies or rescheduling if you are booking far in advance. If you are planning a vacation, it’s likely that you are making plans for yourself and other people.  It may be fun to plan a surprise—a nice dinner or an exciting excursion—for someone who is traveling with you. As tempting as it may be to plan every moment of your vacation to be sure you get in every activity you want to do, resist the urge to over-plan.  A vacation is supposed to be a break, after all, and a little leisure time or room to participate in an unexpected opportunity can make your trip even more fun and exciting. If you have a long list of activities to do or sights to see, rank them based on how important they are to you.  That way, you will know to make time for the items at the top of the list. If you don’t get to every item, you may be able to return to the same vacation spot in the future and finish your wish list.
Summary: Buy a travel guide. Choose activities everyone can participate in. Book special adventures ahead of time. Plan a surprise. Leave some unplanned time. Prioritize sightseeing or activities.
