Recently, Duminil-Copin, Raoufi and Tassion developed a new method to prove sharp phase transition for Voronoi percolation even in higher dimensions. The idea is based on two main steps: For $S_n(0) := \{x \in \mathbb{R}^d : ||x|| = n\}$ and $\theta_n(p) := P_p(0 \leftrightarrow S_n(0))$, they first prove a family of differential inequalities regarding $\theta_n(p)$. Here, they make use of a randomized algorithm, which determines the function $f := 1_{0 \leftrightarrow S_n(0)}$, and of the OSSS inequality, to estimate the variance of $f$. Second they employ a Lemma to $\theta_n(p)$, which verifies the sharp phase transition. In the talk we transfer this method to prove sharp phase transition for confetti percolation in $\mathbb{R}^d \times (- \infty, 0]$.
