Make a toy telescope using toilet paper rolls

Recently my son got interested in astronomy :) Even though he's only almost four, he enjoys watching documentary movies on astronomy, knows the names of all the planets, what a solar eclipse is and much more... That's why we came up with the idea of making a toy telescope. Here's how you can do this:

You will need a lot, but really a lot (15) of toilet paper tubes, an adhesive tape, glue, scissors, nice wrapping paper, images of different planets, stars or constellations (stickers, cut-outs or drawings), and... a bit of free time.

Join 5 tubes into one long tube using the adhesive tape — that will be the telescope tube. Now make the three legs of a tripod  — each one out of three tubes, — by joining them with the tape. Attach the telescope to the tripod, then cut the bottom of the legs at an angle, so that they can stand steadily on a flat surface. Finally, wrap the telescope nicely in wrapping paper. Now you have to decide what you'd like to see and make interchangeable caps with different pictures.

Well, let's make the caps. Make a lengthwise cut in a toilet paper tube, and then cut the tube into 4 or 5 rings. For each ring separate the edges of the lengthwise cut to create a gap of about 1 cm (3/8 inch) and secure with the adhesive tape. Now the ring should fit the front of the telescope tube. Prepare a paper circle that is approx. 2 cm (3/16 inch) wider than the ring in diameter. Glue an image onto the circle, put the ring onto it, then fold edges of the circle up and glue them to the ring. Make several interchangeable caps using the same method. You're set to play :)
