The older kids had to make a contraption that would allow vinegar to pour into some baking soda to make it fizz. No hands. Above is Morgans and below is Victors (Victor went fishing on Friday with the boys so he and Ethan aren't in any of the photos).
The girls Morgan worked with.
Ana's inventions were more decorations. The tissue box holding the heart and the witch in the background.
We asked if Tanya could go since Victor and Ethan were gonge and she had been very curious about what they were doing. They said it was fine. So Friday, Tanya attended with Morgan and she invented an amusement park ride, a type of farris wheel. Ana made a swing like ride (she really liked the swings at Lagoon that she was tall enough to ride this year).
Victor made a roller coaster type ride that the marble goes around and through. Ethans was sort of like a slide with a jump at the bottom so you go flying.
This was Morgan's group wall roller coaster. Below is Ana's groups roller coaster. They wanted to bring them home and I wouldn't let them, thus pictures of everything they did.
