launch pad
today clara and I were partners, we had to build a launching pad for the spaceship aka a water bottle. we have to build a structure that was light enough not to wighed down and strong enough to hold the force of 3 launches. clara and I decided to go with a triangel shape, and it held up well and passed all the tests. we realized that by making somehting not hollow it would withstand better. we also needed a whole lot of glue! we then decided if we could make something even lghted than the popcicle stick one by using skewers on teh same deisghn. the skewers also worked and they were 10 grams lighter than the first one

You gals did a good job reducing mass by using the skewers instead of the popsicle sticks. But don't forget to tie back to the key point. What did this lab have to do with Newton's 3rd law?
