How our spine moves!

We learned that our spine helps us twist, bend and move. Did you know that there are 33 vertebrae in an adults spine. We did an experiment to show how this works and no, no real spines were used here๐Ÿ˜†๐Ÿ˜†!

After placing a pipe cleaner into a straw, we tried to bend and twist it but we found that it was very diff. We took the pipe cleaner out and we cut the straw into 2cm pieces. Next we thread the pipe cleaner through the smaller pieces of straw. We found that it was easier to bend and twist the straw and pipe cleaner. The smaller pieces of straw represents the vertebrae in our spine. Very simple experiment to explain this concept!!
