Ocean layered jelly

An edible depiction of the ocean zones

Eve’s current topic is ‘under the sea’ so we have been looking at the different zones or layers that you can get in the ocean. Check out our other ideas here.

Today’s idea to depict the zones was to make a layered ocean jelly! Eve loves jelly and we thought it would be a great way to show the colours and layers of the ocean.

For this activity you will need;

  • a glass tumbler
  • blue food colouring
  • Black food colouring
  • gelatin (2 sachets)

We got 2 puddings out of these ingredients so if you want less then just halve the amounts.

We started by measuring out 1/2 a pint of hot water and then adding 1/2 a sachet of gelatin to the water. It is important to do it this way round otherwise the gelatin will go lumpy (i speak from experience). Then we took the black food colouring and added a few drops until we got the desired colour. Once thoroughly mixed, we poured the liquid into our glass tumblers to a level we thought was ok for the abyss zone of the ocean (bearing in mind this is the largest of the zones). We then put the glasses in the freezer to speed up the setting process. The liquid took approximately 20 minutes to set.

Now onto the next layer, the midnight zone. We repeated the above process but instead of adding black food colouring we added a few drops of blue until we got a dark blue colour. Now came the tricky part, pouring the blue liquid into the tumbler without disturbing the already existing black layer. The trick is to do it nice and slowly. One you’re happy with your amount, then place the tumblers back into the freezer for another 20 minutes.

The midnight zone being added

Repeat the above process again for the twilight and sunlight zones, just adding less blue food colouring for each layer.

Once completely set you will have an edible depiction of the ocean zones! How good is that!

Now, grab a spoon and enjoy. And tell us what you think.
