BRAAAAAAAAAAAAAAAAAAIIIINS!!! Well, just one brain and it’s not all that delicious if I am honest. HOWEVER, this beaut of a Fizzy Brain Dig is one of those 3 birds, 1 stone activities! Science. Sensory play. Halloween themed.
I bloody love Halloween, so much, but I was over ambitious again this year and thought I’d be able to knock out the 31 days of Halloween. Like last year though, shit happened and here we are. At least we’ve done some Halloween stuff right?!
Baking soda and vinegar is always a winner with kids! Both Iz and I had so much fun playing with our giant baking soda brain outside and it was awesome to see her get her hands in there and squishing everything between her fingers.
The science part of it
When you mix baking soda together, you get a chemical reaction that produces carbon dioxide. Carbon Dioxide is the same stuff that makes sparkling water and soda drinks fizzy!
The sensory play part of it
It taps into sight, touch and sound! You can see, hear and feel it fizzing as well as it being all squishy AND you’ve got the different textures of the bugs you’re hiding.
The Halloween part of it
It’s a brain full of bugs and eyeballs that fizzes… enough said.
What you’ll need
– plastic brain mould (I got ours from Look Sharp)
– 2-3 kgs baking soda (You can get this super cheap from bulk food places such Gilmours or Bin Inn)
– food colouring
– 2-3 litres of vinegar (Countdown do a 3L bottle for $4!)
– Plastic bugs, spiders, eyeballs, bats- things for hiding
– a scooper or tweezers
– something to pop your bugs in
What to do
– Measure out your baking soda by filling your brain mould up! Pop this into a large bowl
– Fill a measuring jug with 250mls of water (you may need more or less) and add in your food colouring
– Pour a little bit of water at a time into your baking soda and mix. You’ll just want enough water to make the baking soda moist. Moist enough that it holds its shape when you squish it together.
– Add a little bit to the bottom of your brain and pack it down. Add a few bugs, cover with more of your baking soda mix, pack it down again and repeat until all of your baking soda mix is gone. You’ll want to make sure you’re packing it down nice and hard.
– Pop your brain in a safe place and leave it to dry overnight.
– Grab a tray or a plate and pop this over the brain mould. VERY CAREFULLY, flip the plate over and your brain should come out. You may notice a few cracks in the mix, this is perfectly normal and you can very gently tap the brain to seal up any cracks. Leave to harden for a few hours.
– When you’re ready to play – head on outside, give them jugs full of vinegar, scoopers and or tweezers and let them explore!
