We love all types of sensory play, but sensory bags can be one of the most relaxing. We’ve made many different types over the past few years, but our new squishy ocean sensory bag has is one of our favourites. Z made this sensory bag himself, with a little guidance from me, and we have attached it to his window to make an easy to access fun sensory activity for him in his room.

To make this ocean sensory bag we used:

  • Large clear zip lock bag
  • Duct tape
  • Hair gel
  • Liquid water colours in blue
  • Loose glitter (we chose green)
  • Wooden ocean shapes
  • Black felt tip / marker pen

How to make an ocean sensory bag

First, we added the hair gel to the ziplock bag. You need enough to fully coat the inside of the bag, but it does not take as much as you might think, since once you start squishing the gel it will spread. Add some, then carefully squish and see whether you need more.

Just drop in a few generous drops, and then squish it all around again. Add more if needed.

Z chose green to make turquoise when combined with the blue gel, and to symbolise the plants at the bottom of the ocean.

We added a layer of duck tape around all of the edges to prevent leaking. At a minimum, you need to add tape to the top of the bag where the opening is.

If you get any small rips or tear in the main part of the bag over time, clear tape will work well to seal that without obscuring the colours. We also used clear tape to attach to the window, which you can see here because of the camera flash but in person you don’t notice too much. I have used clear tape to attach various things to windows and it never damaged my windows so far, and comes off with ease when it’s time to remove that decoration. If you have brand new windows or are unsure then you may want to look into an alternative – everyone’s windows may be slightly different!

Since it’s on a vertical surface, after a couple of days the gel will move further towards the bottom, but this takes time and doesn’t keep happening during play since the gel is pretty thick.

Using liquid water colours really made the colours pretty. This is the brand that we use: UK / US
