first there was ring puzzles, tower of hanoi, etc.

im a high iq but dont do puzzles bc theyre a waste of time. will research them someday.

first of all, there was such a thing as a Foucault pendulum, but it wasnt working today.

seems this is shifting and the blocks falling down.
- why tf does that happen?
- how does it keep swinging??
idk

then we crossed the bridge to the science museum it was 33℃ (91°F)

first we ate gyūtan (beef tongue) at Rikyū in Morioka Station.
⭐ ☆☆☆☆
this differs from gyūtan in yakiniku restaurants. its served with barley rice and tail soup and originated in Sendai. i suspect some japanese dont know.
this was too salty.

went to the Children's Museum of Science in Morioka with mom.

for science, its better to go to a science museum than to read doraemon educational manga imo.
