@that_stem_guy What a Finish!! at the line - virtually a photo finish!!!! Well Done Racers!!
@that_stem_guy Do they blow the balloon up and then place it on the straw to power their vehicle? If so, doesn't the balloon blow off. Very curious. Thanks
@that_stem_guy I'm doing them tomorrow. Wish I'd thought of a Finish banner 😀
