How to Make a Telescope
Search the skies for a long lost planet or a shooting star with this fun telescope project. It’s a great opportunity to teach little ones about space too!
1. To make one of the tubes smaller, cut it open along it’s length. Press it back together with a 1cm overlap and tape back together. Check it fits neatly inside the other tube, if not, adjust the tape until it does.
2. Measure a 5mm x 8cm slit on the taped tube, 1cm from the bottom. Use a craft knife to carefully cut it out.
3. Paint both tubes blue and leave to dry. Use the knife to poke a hole in the bigger tube, 1cm from the end. Place the smaller tube inside and line up the cut out strip with the hole. Insert a brad through the hole and slit to hold in place – you should now be able to extend the telescope (it might take a little wiggling before it runs smoothly!)
4. Decorate the telescope using gold paint and stars. We decorated one with constellations created with dots of gold paint. For the other we created a graduated effect using gold stars and paint.
5. Draw around the larger end of the tube onto a piece of acetate. Fill the circle in with a space scene, such as planets or a rocket. Colour in with Sharpies and cut out.
6. Add a line of glue using a glue gun inside the wider tube, about 2cm from the end. Leave to dry to create a ledge. Place the acetate circle on top and glue in place.
