Over the next week we will be posting lots of Sensory ideas on the SERC website. To start off I thought you may like these easy to make 'calm down' bottles- they can be made this size or would work as well with smaller water bottles.
Watch the glitter swirl and slowly settle in these DIY hush bottles. They made these using the directions posted by Johanna at My Crazy Blessed Life: http://mycrazyblessedlife.com/2011/10/03/relax-bottletime-out-timer/ and they posted about our experience with the bottles here: http://inlieuofpreschool.blogspot.com/2012/06/perfect-hush-bottles.html
