We have a couple of leaks due to the poor quality of our insulator (Cellotape). Since the pipes do not rotate at their joins, glue can also be used to seal these more effectively.

Time for a coda to my #EasterEgg A-Z @britishmuseum: these intricate designs are by a 20-year old student nurse in #Halifax #Yorkshire in 1972. From a #Ukranian #immigrant family, he learnt the art as a child, & gave these eggs to #folklore scholar Venetia Newall 1/3

@HemplandSTEM @LEGO_Group @LEGO_Education @STEMLearningUK @Stemettes @STEMclubs @PathfinderMAT Unfortunately, the video(s) I shot were not great, very much amateur in this regard. I will try to capture some of the details in daylight instead.

@HemplandSTEM @LEGO_Group @LEGO_Education @STEMLearningUK @Stemettes @STEMclubs @PathfinderMAT Thank *you* for the deeply stimulating ideas/challenges, @HemplandSTEM , not only was this fun to build but also there was so much to learn - looking forward to the next challenge!

We used a wooden egg to avoid accidents (on the carpet) over innumerable tests however, any fragile object is compatible with the final installation.

For the week 3 @HemplandSTEM challenge, we got carried away by automation possibilities with Lego Boost and managed a fully automated Easter Egg cable car delivery system! @3Hempland @HemplandPrimary

Around 100BC, the Greeks built a geared mechanism that could:
- Track the motion of the sun, moon and planets
- Predict eclipses
- Adjust for leap years
- Indicate years of Olympic games

Learn how the Antikythera mechanism worked in this week's paper:

How long is a "moment"?

Moment was a medieval unit of time. 1 day was divided into 24 hours and 1 h was equal to 12 lengths of the period from sunrise to sunset. 1 h was divided into 4 puncta, 10 minuta, or 40 momenta. Considering an average 12 solar hours

1 moment = 90 seconds
