    Apple Bobbing – Halloween Game

    October 29, 2012 By Emma Vanstone 10 Comments

    Apple bobbing is a traditional Halloween/Autumn game, with some interesting science behind it.

    We used a large container filled to near the top with water, I removed the stalk so it didn’t poke anyone in the face, and asked the children to try to pick up the apple with their teeth.

    A metal tub filled with water and apples for Apple Bobbing.

    The first time everyone tried they pushed the apple down when trying to bite it, and then it bobbed up again to the surface. My 4 year old cheated and held it to get a bite, after that it was much easier to get a grip on the apple!

    Why is apple bobbing so hard?

    Whether an object floats or sinks depends on its density. Density is how tightly packed the material inside an object is. Just because something is heavy does not mean it will sink. For example, ships are very heavy but not very dense so they float.

    For an object to sink it must be more dense than the water. The apple is less dense than water and so bobs back up to the surface after being pushed down.

    Try with different kinds of apples? Are waxy apples easier or harder to grip? What if you chopped the apples in half?

      I tried this with grapes once – they sink!

      Two alternative ideas for you that work better for younger cildren:

      1: set fruit (or Haribo) in shallow trays of jelly instead. Less of a challenge for little ones and they can always get the fruit out of the “slime” with their fingers if they dont want to put their faces in!

      2: pile a few cups of flour on to a tea plate and set a big marshmallow on the top, pushing it into the flour slightly. The children then try to pick it out with their teeth and inevitably end up with flour on their nose or (if they are brave) ghostly faces!

      3: hang pieces of apple up on a washing line – doughnuts and party rings work well too for this – children have to jump rather than bob for apples

      Once I have tried same type of game at home when I was little with friends, it was fun but I was very little to think about the reason behind the science of this.
