We remembered how we made the top explode from the bottle when we added vinegar and baking soda. We put a straw under the boat so the ................ Will come out. can you remember?
now we are adding the vinegar
And the baking soda.
What do you see coming out of the bottle? Did it make the boat move? What was coming out?
Perhaps if you ask you will be able to make a boat at home with your family.
