It will shrink-get smaller.

Detailed explanation-1: -There is a much higher water concentration in the egg than in the syrup so water will pass in the opposite direction. This means that the egg will shrink in size. The corn syrup is a hypertonic liquid, ie. very concentrated with not much water compared to the egg.
Detailed explanation-2: -An egg with a dissolved shell is placed in pure water for 48 hours. The egg will gain water and swell.
Detailed explanation-3: -Because it allows small molecules, such as water, to pass through but not larger molecules, such as those in corn syrup. more water is drawn up into the thistle tube with higher concentrations of corn syrup. the ability of a solution to change the volume of a cell through osmosis.
Detailed explanation-4: -Water moves into and out of cells by osmosis. If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic.
Detailed explanation-5: -1: Osmosis: In osmosis, water always moves from an area of higher water concentration to one of lower concentration.
