Boy's Science Experiment at Home

Never thought I would stop myself from science experiments and question using up supplies in case we need them “later”... . Sure takes away some of the fun. I mean, how did early pioneers make “lava lamps” if they had to ride for days to get more vinegar and baking soda. Nevermind cooking down the cow for lard to make oil for floating. . . I guess we need to find some non-kitchen experiments. I might need some vinegar to pickle some vegetables later... but I would need vegetables...
