I can’t remember what I was making, but my daughter was sitting with me making things too – this one she made from her memory of something she had seen in a book. The only thing I helped her with was painting the yellow strips around the edges of the tubes, she did everything else herself.
At first I did not take photos of the steps and it was just a bit hard to follow what was happening, so we repeated the steps so we could get some photos up here – we did miss out the painting step though as you can see what it looks like from our first painted telescope..
You need three cardboard tubes, or one long one cut into three equal lengths. This is made from recycled some toilet paper tubes. You will also need some ribbon. You need four equal lengths of ribbon, each just a bit longer than the length of the tube.
The first task is to paint all the tubes, we painted them with a yellow rim around each one, it turns out to be very effective having that bit painted a different color.
Cut two of the tubes down the length.
Roll them a little tighter so that they have a smaller circumference and tape them along the cut edge. The aim is to have the three of them all fit together – so one will need to be a bit smaller than than the big one, and then the other a little smaller again.
Tape the top of two pieces of ribbon to the inside bottom of the smallest tube – on opposite sides of the tube.
Then push the end of that smallest tube into the top of the middle sized tube and drop the ribbon down the inside of the middle sized tube and tape it to the bottom of the middle sized tube, so that when you pull the tubes apart, they can only go so far as they are held together by the ribbon.
Repeat that with the middle sized and largest tube. You will end up with the three of them nested inside each other and when pulled apart they only go as far as pictured as they are held together by the ribbon.
