Astro Nappy!

This week has been Science week and year 4 had to investigate the best material to make a nappy for an astronaut. Astronauts can sometimes be on a spacewalk out of the rocket for up to 8 hours so it is important they have a good nappy which will stop any leaks.

We discussed ideas and decided to test baby wipes, kitchen roll, sponge, cotton wool, felt and wadding.

our results showed that cotton wool and baby wipes held the most water. We decided to combine these two materials to create a super dry nappy.
