My team, did a lab to see how much Slat it took to Float a Orange Crayon. We did a Orange Crayon Sized at 2cm, 4cm and 6cm.  With 150ml of Water in a Beaker. We thought it would all float at the same time becauseit all has the same density but it didnt 2cm floated in 2 spoonfuls of salt . 4cm floated in 2cm and 6cm in 4 spoonfuls. It was wierd results but we thought it was going to all be the same but we were wrong.
