Description: cooking with chemistry this is the first in a series of two cooking videos we're doing to

A two-part cooking-chemistry video celebrating 100 videos, centered on raspberries to make a raspberry sponge cake with a mousse filling.
Make meringue from two egg whites with sugar and cream of tartar, ensuring clean equipment for good volume.
Experiment with raspberries: an initial raspberry and syrup test, followed by a stronger dehydration attempt using phosphorus pentoxide to induce reaction.
Prepare sponge cake batter with egg yolk, sugar, vanilla, and low-gluten flour; fold in half the meringue and all the flour, then the rest of the meringue; bake at about 170°C for ~15 minutes and cut into four circles.
Make raspberry sauce by simmering raspberries with sugar, then add gelatin, heat, and strain to remove pits; reheat with pits and strain again to concentrate flavor.
Whip cream (high fat) and chill the raspberry juice before folding it into the cream along with the remaining meringue to form a raspberry mousse.
Assemble the cake in paper molds wrapped with greaseproof paper, layering sponge, raspberry juice, sponge, and mousse; chill overnight to set.
Conclude with a dramatic experiment: combine sulfuric acid and hydrogen peroxide to form piranha solution, observe vigorous reaction, and discuss its strong oxidizing properties before finishing the dish with whipped cream.
