Raghav decided that he was getting back to Lego today and was all excited to build a space centre and launch pad to display for Navaratri (he had already built the space shuttle a few months ago). As he was finishing, he realised that the control centre needed a huge radar dish, which he did not have ready in Lego.
So he decided to make one. It had to be a giant one! While he was building it with the Lego pieces he had, he realised that it hardly looked like a radar dish and was more like a giant flower :)....but he really wanted to make it look like one. I suggested we use paper to cover the gaps, and he agreed to give it a try. So here is what he set out to do.....it was challenging and fun! And he figured out that there was so much measurement involved :) He wanted a perfect circle and since we could not find anything around the house that matched the size exactly, out came the ruler and the compass (from the ancient geometry box), for the first time in all these years!

| the basic structure for the radar dish made with lego |

| measuring the outer radius |
 | |
| adjusting the compass to get the radius |
 | ||
| done! - got the exact measurement |
 |
| drawing the outer circle with the compass |
 |
| drawing the inner circle after measuring it in the same way |

| immersed in cutting |

 |
| all the cutting done! |
 |
| checking to see how it fits |
 |
| fixing the paper onto the lego structure with cellotape |
 |
| all stuck! |
 |
| bending it to look like a radar dish |
 |
| cutting another one for the back side |
 |
| fixing loops of cellotape |
 |
| sticking the second circle onto the back |
 |
| bending the structure to resemble a dish |
 |
| it worked! |
 |
| the giant radar dish is fixed! |
 |
| mission accomplished! |
