Valli and the pink button

Valli meets the boys

Half-term trip to Skanda Vale to meet Valli and test out the water valve system.

I constructed a simple plastic button from layers of tinfoil with foam sandwiched in the middle - similar to a dancemat - requiring a gentle press to make the circuit.  We fixed it to the ceiling next to Valli's enclosure so she could reach it with her trunk. 

Pressing the pink button

On the floor above, the button was connected to an Arduino input pin.  The output activated a water valve via a relay switch, sending a strong spray of cool water along a hosepipe and down onto the rubber mat where Valli usually has a wash.

The water was on for a 30 second burst, then had to be re-activated.  She was persuaded to use the button a few times, but moved sharply away from the water spray - obviously not a strong motivation!

Brother Stefan will plumb in the pipework properly so we can test different interfaces that she might (or might not) like to use.

Homage to Evil Mad Scientist.  We scuppered old motors from toy cars instead of using mobile pagers.  The manufactured track is from a Hexbug Nano set.

pH ART

A day at Chesterton Primary showing Year 2 kids how to make their own litmus paper using red cabbage.

Chop and boil the cabbage for 10 min, then paint the dark red juice onto blotting paper.  Leave it to dry, or warm very gently in oven.  When it's dry, you can cut it into strips.

Children painting with lemon and bicarb

Use the strips for testing various liquids - try milk, oven cleaner, lemon juice, baking soda, saliva etc.

The children numbered their strips and wrote down what they had tested.  When they went back to class, they did a presentation and explained how some things are acid, some are alkali and some are neutral.

At home, we used lemon juice, bicarbonate of soda and tea as finger paints.
