Kash and Sevan were back to help Mr F in his front garden today after tackling the back last time. Weeding the all concrete, sloped front garden sounded simple. There were lots of cracks and uneven surfaces that the weeds had gotten into though and the south-east facing from garden was catching lots of sun too, draining the team's energy. There was a lot more work than Mr F and his wife expected.

Pulling the weeds was the most rewarding and most difficult way to clear the concrete. Seeing the roots rip out of the ground was satisfying, knowing that they wouldn't be able to grow back quickly. If the wouldn't pull out, then Kash and Sevan resorted to cutting or scraping, which wouldn't last as long.

As the GoodGymers were working hard in the heat, Mr F's wife brought them some cold water with elephant shaped ice cubes. After a couple of minutes, the cubes had vanished in the heat and elephants were extinct, or maybe they were actually mammoths and their ice age had come to an end. Mammoth ice cubes for a mammoth task?

After an hour, the front garden was clear, so work moved to the back. Kash twisted more weeds from around Mr F's prized rose bushes and Sevan cleared the area in front of the shed. They achieved a lot and there was plenty more work still to be done. They left Mr F really happy with the result, especially the transformation at the front, before Kash and Sevan ran off to their last mission of the day.

Mrs P had what looked like a simple problem. There used to be a screw holding the light cover in place on her cooker hood that had dropped somewhere behind the cooker. She'd decided that it was lost, so she had a scavenged collection of screws plus a brand new pack for Holdilocks to use to keep the plastic cover in place.

Holdilocks started with the smallest screw which was too small to stay in the screw hole. He worked his way up through the screw sizes with none of them fitting until he tried the largest one, which was too large to fit in the hole. As there was no "just right" option and the cooker hood was made of sheet metal, Holdilocks decided to use the Holdilocks principle which says:

If the Goldilocks principle doesn't work and there is no "just right", then judiciously try more power to make things hold together

By defining and using his own principle, Holdilocks made the large screw fit by increasing the size of the hole and the hold on the cover became just right.
